I started having charging problems last summer and thought it was just a bad ground.Have had the truck out for a couple clear out the mothball runs and am still having problems.On the first trip ammeter showed generator not charging till we hit a bump then it kept working for the rest of the 45 minute trip.Tonight it is showing no charge again.Generator is converted to 12v and tests ok,regulator as well.this is on a 54 with the original 235 and most of the wiring is the same vintage.Is it possible it could still be a grounding problem or will the wiring be the most likely source of my troubles? Any help is greatly appreciated . Thanks Murray

First time I saw this truck I said "That's the one!"
