That will work as long as the seat frame is isolated from the motor/control grounds. But then you can't use one of those 6/12 volt batteries.

Don't screw around with different combinations that may leave you stranded in the woods. Convert the whole thing to 12 volts negative ground and be done with it. Do it the correct way. Very easy to do. Get an aftermarket harness and rewire the car to modern standards.

Yeah, I will probably convert it to a 12 volt system...I was just researching my options to see if there was anything easier that I could do.

If anybody has any good sites/threads/info about a 6 volt pos to 12 volt neg conversion that would be much appreciated!
