Re: Starter engages when ignition turned to on.

The 12v supply to the coil is operating only when the starter solenoid engages. When the engine starts and the key released the "run" relay is activated and the start relay switched off. The coil is then running on 6v via the resistor.. Only the 6v supply comes from the relay so in theory the engine...

Re: Heated rear windscreen voltage drop

Try running the engine at about 3,000 rpm. It's possible that at 1,500 engine rpm the alternator is not on full charge,
What's the reading across the battery terminals? It should be around 14v.
The alternator runs twice engine rpm.

Number Plate Rules

I read this on a Land Rover club forum today and it is genuine. It's been always assumed that once a vehicle has been taxed as historic then black and silver number plates can be fitted. When I ordered a set in 2016, for the Land Rover, the supplier entered the registration number into his computer ...

Re: Draining fuel

Some people will say that modern petrol is no good after it has stood for 2 months. My Austin 7 started easily enough recently after a year standing, so it's anybody's guess, but a few years is too long! I would have thought that the easiest way to drain the tank would be to disconnect the fuel pip...

Re: Exhaust manifold nuts

I've got MGOC brass barrel nuts on the manifold to head on my BGT. They will fit the downpipe studs on the standard cast iron manifold and interestingly the manifold to downpipe studs on my 1975 Series 3 Land Rover. Being longer than the studs, they stop corrosion on the studs and I can remove the c...

Re: Overheating

I've had a reply from Peter Burgess and he reckons it's a cooling issue as, like I thought, coolant would be expelled if the system was being pressurized. Years ago I had overheating with no water loss. It turned out to be the impeller drive on the water pump had sheared. When I've got the Land Rove...

Re: Overheating

An update. I've drained the coolant and disconnected the hoses and linkages but with a new puppy arriving, things have been put on hold. This morning I rang Peter Burgess and spoke to Simon. He thought it was puzzling situation and suggested I do a compression test. I said I had and told him the res...

Re: heat effect on ignition system mgb.

Am I right in thinking you've replaced the fuel pump? If so have you connected the fuel lines the right way round to the pump?

Re: Webber DCOE-45 + 123 ignition/vacuum advance

Don't take the vacuum advance pick up from the inlet manifold as rubber bumper B's had. It needs to be on the air filter side of the throttle disc close to the disc.
