This was a jolly good show despite this mornings rather incliment weather. I arrived at 9 o'clock in pouring rain and was one of 5 cars on the field. The rain stopped half an hour later and then lots of vehicles magically appeared The first 6 cars on the field with thier hardcore owners. I had a crack at some arty farty pictures but annoyingly the stewards hadn't lined all the cars up perfectly. One of many Morris minors on the field A lovely smart Triumph TR4A More arty farty can you guess what the car is? A lovely honest example of a well used volvo amazon Now this was a refreshing sight. Now I know the general consensus is that rubber bumper Bs don't look good, but I feel that every car has its place and shouldn't be made into something that it is not. To start with I thought that this was a home built conversion but later found out that it is an original London Transport service vehicle. A bedford aviation fuel tanker which sounded rather odd two stroke? Series 2 landy and a Ford Thames van A very rare sight was this Standard 10 pick up which for some unknown reason had a tow ball mounted upside down Its owner also randomly jumped in front of the camera ;D This morris minor van was really annoying me can anyone spot why? 1972 ERF 8 legger powered by a Gardner 180 diesel. This Bristol was just gorgeous. 5 litre V8 and 7 year long resto, please please please can I have it? Here we have an absolutely imacculate completly original mk5 cortina ghia. 700 miles from new and even still hads its polythene seat covers on Paul

MacP - you can understand the confusion re the Minor - the Austin versions are very rare indeed.
The Standard Pick-up with the towbar - I think that might have been one of the now very rare Australian versions.
And FB Victors - a little known true fact about me... Such was my excitement that within hours of my mum and dad taking a test drive in a (then) brand new one, I appeared in this world much earlier than expected. Could explain a lot. (And yes, they went on to buy one and over the next 15 years or so, a succession of Victors. Happy days.)

Lovely pictures Paul. If I had my anorak on then I'd be saying the Cortina is a mk 4 not 5, but I don't so I shan't! Well done for flying the DAF flag again.

A teacher of mine had a 'tina Mk4 in that colour, but with the tan colour vinyl roof - which looked pretty horrible even in the seventies. (Trivia link 1) Though Ford also did a red vinyl roof for the Mk3's that was pretty frightful. That teacher went on to trade it in for a shiny new Lada 1500 estate - which he said was a better drive! He towed a caravan with the Lada, and to save himself time he had a towbar fitted on the front! (Not sure if that's strictly legal??) So he could manoeuvre it into it's parking spot without having to reverse it! (spurious link 2)

KEN im ordering you to confiscate Snowstrops mobile phone!! She has been talking to Gladys and is a very bad influence on her ;D Ive had a bit of a missfire recently so thought simples lets give a simple service. Plugs out cleaned and regapped, New set of points and condensor. The good news the missfire has gone and she is quieter smoother and a bit more powerfull than before The bad news now it takes several attempts to get her to fire into life and then when she does her idle is as slow as a snail on sleeping pills. More fiddling tomorrow before I leave for a 2 day car show.

I haven't touched the timing though. Just changed the condensor and replaced a set of burnt points. Seeing as the timing setting hasn't been changed im presuming that the closing points would throw it out and regapping them should put it back.

No, whenever you disturb the points the timing will need resetting. Wear at the plastic "heel" or the contact surfaces will alter timing for a given gap and the old set will have had both. In fact, even two new sets won't be identical enough to give the same timing just by setting the gap because they're not exactly precision made!

I have just got back from a brilliant show and am pleased to report the Gladys behaved imppecably after setting the timing and generated a great deal of interest. (Enough for the show president to ask me to give all the stewards rides round the show field!!)

I wondered how loud drive belts can be when they let go. The anwser is very loud indeed, Dad heard it go 3 cars behind ;D

Sorry to hear that Paul. Good job Gladys displays the 'beware of flying rubber' sticker for the benefit of the following traffic...

Just looked under the car. Both belts are still there! So the very loud squeeling up every hill after a big bang is making wonder what on earth is causing it

Broken halfshaft (loud bang) so one belt is taking all the strain now (squeals).

Yep could be Joe, Paul jack up each rear wheel and check for FREE movement, dont reverse up onto ramps(I know got the TEE shirt)

Its not a half shaft. Cant turn either rear wheel independently of the other. But right hand drive belt has gone slack and left hand is still taught. Wonder if the kevlar reinforcing in the belt has gone.

If it had, the belt would be spread all over the roadside Paul.
If the drive-shafts are intact and the belts are intact then about the only things that could make one slack while the other one's tight are a serious misalignment of the pulleys (ie: something's broken loose so the right-hand pulleys are closer together than they should be), the spring failing in the r/h secondary, or one of the rh pulley sheaves failing near it's hub (same effect as spring breaking)
You should be able to see the first because there'd be something very major broken and you should be able to check the second because if it's happened you'll be able to spread the secondary by hand - which is normally impossible. Never heard of the third possibility happening in use (as opposed to servicing mistakes) but figured it should be included to cover all bases.

Gladys is once again off the road due to a failed charging system. I think im going to need some new parts.
Dynamo brushes are very low so best case its just replace those.
Unfortunatly ive spotted some signs of arcing on the amature and have no way of testing it. Dynamo is kicking out nothing at all, so I cannot tell if its being regulated properly so the regulator may need changing as well. If thats the case I may as well alternator convert it. How much work would it be to graft in a 46 charging circuit?

Got back from holiday read cars trying to kill me week ;D . Put some new brushes in the new ones are a good 1/2 inch longer than the old ones. Unfortunalty the car is still not charging.
With the engine running I put a voltmeter between each dynamo and earth and picked up nothing. Then put the voltmeter across the DF and D+ terminals and still picked up no voltage.
So Im going to have to replace the commutator or the voltage regulator

Standard dynamo test:
1. Disconnect both terminals on the dynamo from the loom
2. Connect them to each other
3. Start engine
4. Connect voltmeter between the linked terminals and earth.
The dynamo is now running completely unregulated and will produce as much voltage as it can. If you get about 20v or more then the dynamo is guaranteed ok.
If you get less then it's guaranteed not ok.
If you get a negative voltage (with the voltmeter connected +ve to the dynamo and -ve to earth) then the dynamo has been reverse polarised for some reason and is now trying to be a positive earth unit. In which case disconnect the two terminals from each other and connect a wire to the battery +ve. Flash this wire to the field terminal of the dynamo (the smaller one) 2 or 3 times and then try the test again (remembering to connect the two terminals together again). You should now get a good high voltage output.
If you get a "good" result from this test then the fault is either the voltage regulator or (more likely) the wiring to / from the regulator. Make sure all connections (including where the regulator earths through one of it's mounting screws) are absolutely spotless and that the wires themselves aren't broken internally - use an ohmmeter to check continuity from the regulator to the other end of each wire. If the wiring is good then the regulator isn't.
If he regulator is bad then remove it's top and run a piece of fine glasspaper between each set of contacts inside it (wet-or-dry works but glasspaper is better cos it doesn't leave nasty dust behind). Do NOT bend or strain anything inside while doing this. Once the contacts are clean, reconnect and try again.

Right dynamo is not putting anything at all out. So I must be needing a new armature. Does anyone know the part number? I think I will change the regulator at the same time as I am told that a problem dynamo can kill the regulator and vica versa.
Got to do this quick as I need her on the road for the WWD weekend on friday. Im hoping to see a few daffers there.

If there's no output from the dynamo then it could be the armature or the field coils, Paul. Unless you can test them (fairly straightforward with a multimeter but a bit in-depth to describe on a quick forum post - especially for the armature) you're much better off replacing the whole dynamo.

Then armature has noticable burning on one of the segments. But im just gonna change the dynamo anyone got one?

Think I've got an untested one here, but wouldn't be able to get it posted to you before the end of the week I'm afraid. Before changing it, though, try testing it again with the field coil terminal (the small one) connected to battery +ve. If for any reason the dynamo has managed to de-polarise completely this should give an output similar to connecting the two terminals of a good one. If you find that you have an output with a +ve feed to the field terminal then flash it as if it was reverse polarised and it should re-magnetise. As for burning on the commutator, some is fairly normal especially if brushes have worn right down, because they tend to spark a lot at that point. As long as the segments are intact and in place, clean it up gently with glasspaper (or wet & dry) so it's smooth for the brushes to run on and it's unlikely to cause a problem. Despite their reputation, dynamos are almost un-killable. If they fail it's generally either from serious overloading or a manufacturing problem - in which case they don't last as long as yours has so far

Well this is the last ever update of Gladys in Lampeter as tomorrow morning she leaves for the last time!
Anyway the reason she hadn't already gone was due to an electrical fault preventing her from charging. When Mark arrived on tuesday he brought with him a known good dynamo from a 33. This was fitted to Gladys and made absolutly sod all difference. Knowing she had a full battery we took her on a 5 mile test drive where apart from blinding me with her generator light she performed as usual without fault.
Because it was due to rain and it was getting dark we thought it was a bad idea to try and drive her to Bristol with a non charging battery so I took Mark back to the railway station.
Today I investigated further and sparks and smoke coming from the regulator box told me it was shot. Now I had the option of a known good Lucas regulator which I was unsure of fitting so didn't or to convert her to an alternator which is what I did.
Cue a trip to a friends workshop to find one Lucas alternator with built in regulator that was turning freely. Swapped the serpentine pulley for a V pulley which sadly is a tad smaller than the one on her dynamo but does work. This was due to go for scrap so was donated free of charge. Then a trip down to the local motorfactors for some suitable spade connectors some 40amp wire and crimp joiners.
2nd stroke of luck the alternator would bolt up with the original adjustment bracket and the pulleys where correctly aligned. I had to reroute the pump to carb fuel line as it wouldn't clear the alternator in its standard form and some new bolts have seen the alternator fitted and in place.
Then came the wiring.
First take the ring terminals off the field and remove the +ve wire and fit a standard size spade connector and connect to the smaller warning light terminal on the alternator.
With the fresh wire run a live to the battery possitive to the other much larger spade on the alternator.
At the regulator end connect the field and warning light wires so that the warning light wire ran direct to the alternator outside the regulator.
Now on the regulator the positive terminal had two wires attached to it one direct from the battery and one to the loom. These where removed from the regulator and connected with a suitable crimp terminal. So that the loom was live and the warning light has power.
Then tested. Reconnected battery and turned ignition key to ignition and generator warning light comes on. Fire up engine and give a quick rev up and the warning goes out and stays out. Switch of engine and warning light glows for a moment before extinguishing. All looks to be working as it should.
So then I packed up my tools and took her for a test drive. Wipers now work faster than before and indicators flash like they did when I first got her. Only one niggle that is easy to live with. If you fire her up and just let her idle the warning light is on, as soon as you rev her a little bit it goes out and stays out even when back to idle.
I think we can say jobs a good un. I then changed the vaccum hoses on the vario and hopefully all will be well for her new owner.
Bye bye Gladys I will miss you but I know you are going to a good home.
Paul
p.s. Howards 33 dynamo when put next to Glady's original is different as are the part numbers so maybe it just wasn't suitable.
