Re: dead moggy

Sorry for late reply, I’ve been out. I asked about the type of starter switch because the rest of the car can be dead with a working pull switch. Yes the two fuses in the fuse box are 35 Amp. I see things have progressed, you have found the weakest link that has blown. It is good to know it has save...

Re: dead moggy

The wiring of the Minor evolved over the years, one addition was the 15 amp fuse in a plastic bayonet type fuse holder, this fuse is for the side/tail/number plate lights. Geoberni’s car doesn’t have this fuse. You say it now turns over, has your car got a pull starter switch or does the starter ope...

Re: Caterpillar

Snap!
Taken last year almost to the day. I added a tape measure for scale.

Re: Gearbox prices

The pickup in Poolguy’s link has an interesting modification to the heater tap.
Take a look at the engine bay, the tap is attached to the bottom hose tee, the metal hose that runs beside the rocker cover has been removed.

Re: Enquiry

Waveband change switches can play up with lack of use, may be worth pushing the switches a few times to see if it springs into life.
Other to that it is more serious, capacitors can fail with lack of use and Germanium transistors can fail with age.
Sorry that it didn't work :(

Re: Spotted today.

Thanks Paul, I did a little search on here and it has a Maestro engine fitted, also was mentioned somewhere that the long inlet manifold is supposed to increase torque.

Re: Spotted today.

Thanks for posting the photos of some fine vehicles, amongst them I spotted this interesting carb setup, it has a MMOC sticker on the windscreen. Hope you don't mind me copying and cropping it....

Re: Enquiry

Thanks Les, If you haven’t already it might be worth trying it on the bench to see if this 48ish year old girl works. I’d hazard a guess that you haven’t got a current limited power supply so hook it up to a battery via a low value fuse of around 1 amp for initial testing and 2 amp for final install...

Re: Enquiry

Breaking news, I’ve tracked down some circuit diagrams online, both Wolfsburg but with an output stage similar to yours, one using AD161/162 has an output impedance of 5.8 ohms most likely the 8 ohm model as 5.8 ohm speakers are not readily available, and one using the slightly better rated AD156/15...

Re: Enquiry

Any full range speaker over 5W will be fine but don’t go too high as they can take more driving for the same volume.
One important thing is the Sensitivity or Efficiency, Measured in decibels from 1 Meter away being driven with 1 Watt.
Remember every 3dB is a doubling in sound output.

Re: Enquiry

Thanks Les, they are indeed Germanium Transistors AD156 and AD157, better spec than AD161/162 but still not great. Play it safe and use an 8 ohm speaker or two 4 ohm speakers in series.

Re: Enquiry

I expect the change from 8 ohm to 4 ohm coincides with the change from Germanium to Silicon output transistors in the late 60’s early 70’s. Both types of transistors suffer from thermal runaway but the earlier Germanium are far worse and are generally lower powered. Thermal runaway is where the base...

Re: SERVO FITMENT

Standard drum brakes by design/position of the cylinders have a self-servo effect on the front wheels when traveling forwards. Discs don’t have this effect. I suppose there is a perceived better braking with lighter brake pedal force with a servo more like a modern car that have too much servo assis...

Re: Running fast when hot

Has your butterfly got a small valve on it?
These can leak air and cause idle problems and are best soldered closed.
I had this years ago on a Marina.
They are used to reduce emissions on over run.
Don’t forget to check your dashpot oil.

Re: Size of PRV domed nut?

If the gauge you bought goes up to 75 psi then yes it does look like 1/8 BSP the same as the Smiths gauges. The pipe fitting is sealed to the gauge with a small fibre washer.

Re: Dead Eletrics

The best approach would be to turn on the headlights to give the system a load, multimeters draw negligible current and can give confusing results where high resistance connections are concerned. Then check the voltages again with the headlights on starting at the battery. It could be a poor connect...
