I have a Willys MB that I purchased 18 months ago. It has been changed to 12 volt.
It starts up first time when the battery is fully charged.
Over a period of weeks the battery seems to lose its charge. (It starts up ok, I take it for a drive, but once it is switched off it will not start without a jump or push starting, then it runs alright until I have to stop again)
I thought it must be the battery so I purchased a new one, but the problem is still there.
According to my meter there is voltage coming from the dynamo - is it possible that it could still be set up for 6 volt charging through the voltage relay? Any help would be appreciated.
Cheers
Chris
