Converting ww2 mb wills jeep from 6 volt to 12 volt

hHi All

I am changing my 1942 MB Willys Jeep from a 6 volt system to a 12 volt system. After a quick inspection I believe I can change to an Alternator with regulator built in, doing away with the large 6 volt mounted regulator on the mud guard, I will have to change the coil and globes and front sealed beams.

I will have to make some modification when fitting an Alternator so the pullys for the fan belt all line up. I am wondering if anyone out there has done a convertion and maybe give me a few hints and what I actually need to do. I have been told that going 12 volts will make it easier to start and keep the battery charged.

Any advise or pictures of convertions will be very much appreciated.

Cheers

no need to change dynamo, I have converted all my jeeps to 12v. and as long as your dynamo is putting out about 13.5 volts it will work o.k. all you need is a regulator from a morris 1000 or similar. a true 12volt coil and change the bulbs. My jeeps have been run like this for 30 odd years. john

Thank you for the advice, makes things easier when someone has already done the conversion and allis working OK.

This may help too. Circuit for the fuel gauge. Apologies for the grainy appearance but the schematic should be OK to read.

There is some thing to do with earthing. If it is sorted out you will fix the hard starting thing . I suggest you go to the G503 site, and do some research in the technical section.

That's a page from my old fuel gauge article. It did the rounds in a few MV mags , Army Motors and the MVT mag Windscreen ... and the Dutch KTR mag .... translated too !

G'day Mike,

Valuable articles like this example seem to live on forever. I scanned this one years ago just in case I needed it for future reference. Well done Mike and thanks.
