Re: Starter Motors for MGB's with Ballast Resistor Ignition.

Wow. Some stuff here. Vic. Aye, the 12v ignition supply line needs to be checked out, but I can't do this until I'm allowed out of lockdown owing to difficulty getting at the solenoid. You and Charles appear to disagree about whether or not the 6v ignition supply line is cut off during cranking. Edi...

Re: Starter Motors for MGB's with Ballast Resistor Ignition.

I can't get at the solenoid connections at the moment Charles so that will have to wait until I can get the car on my lift.

I'll check out the fuse box connections though.

Re: Starter Motors for MGB's with Ballast Resistor Ignition.

Thanks Charles. The securing clip for the coil does say Lucas DLB102, which is a ballasted coil. May not be the one supplied with the coil. Meter readings between low tension terminals 1.5ohms and between low and hi tension 9kohms, which I took to indicate "6v" coil. The running voltage 11v is a mys...

Re: Starter Motors for MGB's with Ballast Resistor Ignition.

Hi Charles ta for the input. The coil doesn't have any id. Any meter tests to determine voltage? The car has done a few 000 miles in this state with no problems including a few several hour continuous runs. It was only this thread that got me checking! Wiring appears to be unmolested, but I can't ge...

Re: Starter Motors for MGB's with Ballast Resistor Ignition.

Do you ever wish that you hadn't started something? At the ignition on position, there is 6.3 volts at the coil which seems OK. On oerating the starter, the voltage is all over the place 2 to 13 volts. Engine running shows 11 volts at the coil and 13.6 volts on the car voltmeter. The car has been ru...

Re: Starter Motors for MGB's with Ballast Resistor Ignition.

A very interesting thread. I've had my 1978 gt for 2 years now. It has always had an unusual way to start. It will only start when the ignition key is returned to the run position. When I first got the car, it would churn over for ages not firing. I gradually realised that it only fired when the key...

Re: Tin Pellets.

Thanks for that Ian.

Is there a reliable way to find out which of the many substitutes now available do work? Independant testing etc.

Re: Tin Pellets.

Interesting post. Whilst I totally agree with you that the pellets thing is probably a con, it occurs to me that somewhere in the process of making leaded petrol, lead is added to the mix. If it was added to the mix then, why is it not possible to add it somehow today? Whoever solves this problem wi...

Re: oil draining back if left for a few days

When I changed my oil and filter last year, the oil pressure went down from 70 to 60, and took its time to register on the gauge. It might have been on here that someone suggested changing the filter again - bingo, pressure back up to 70 and no delay. Can't remember the make of the dud filter, but t...

Re: Largest Engine Capacity.

I had a 1960 Cadillac Sedan Deville 390cu.ins. about 6.5 litres. Had it from 1990 to 2005. If driven with a very light foot, I got very nearly 20 mpg on a trip round Argyll and Isle of Mull. Local trips though 14 or 15 mpg.
Lovely car to drive, and if required had scary acceleration!
