Hi Guys, I just got my 55.1st series pickup to run and drive and stop. took it around the the block for the first time in many years. It feels good. My question is. Does any one know for sure if this truck could have been built 12v. The last owner says it was but he has proven not to be the most honorably man I have ever met. The bulbs are all 12v as is the generator. But while it runs the ampmeter is jumping down to full discharge and then back up constantly. I dont see any resistors mounted anywhere and cant find any markings on the voltage regulator. I want to go to 12v alternater soon but dont want to burn anything.
