I finally got to work on the '56 some this weekend, cleaning cooling system etc. Started the truck and run up to tempature, when I shut it off with the switch, I heard a motor running, it was the generator. I have had the generator rebuilt and a new regulator from a good shop in town, what could be causing this ?...I have a battery disconnect but as soon as I connect it , the generator starts turning...Help !Truck starts and runs fine, shows charging, but when I shut it off, generator runs on even though the engine is off
