Good evening all.
I have a 1959 Ford 641 Workmaster. I bought it about 3 years ago. It is still 6 volt system with generator.
It has ran and started great the whole time I have owned it. All the wiring looks to be in great shape. Last year the fuel gauge stopped working. I replaced it and the sending unit. It shows full or empty depending on how I wire it. I gave up on it.
The battery failed last week.
With the help of you guys here I have discovered the battery had been put in as a negative ground by the previous owner. I have been bench testing the fuel gauge and sending unit with the new battery. I can get it to work if I touch the sending unit to the positive post with the ground wire on the positive post and the "B" wire on the negative post. This is with a new battery that has not been reverse charged.
If I drain the battery and reverse charge will the fuel gauge work?
I believe I will have to reverse the generator polarity. How do I do that?
Will the coil wires need to be reversed?
