Looking for some direction on where to start my troubleshooting on this one. I was driving my ‘51 half ton yesterday and the engine died, tried to restart and the battery was gone. Tried to jump, engine turned over but would not start. Truck was in a high traffic area so I had to get it towed home. Engine is a ’55 second generation 235 and all 12 volt elec items were transferred over with it - coil, distributor, generator, voltage reg. Battery is brand new, gas tank is full. I’m thinking that the voltage reg is the culprit but thought I should be able to jump start even if the voltage reg went bad. Also can I trouble shoot a voltage reg with just a standard voltage/ohm meter? Thanks much.
