I got a question about my 7.3L F350 engine. I just got the truck (its a '94) and it had been starting great. The other night on the way to plow it started right up.. I hooked up my trailer to haul my JD that I use for blowing snow and shut the truck off with the running lights on for maybe 10min. When I went to re-start it there was nothing.. after lots of attepts at charging it, boosting it Im not sure whats wrong. At first it would turn over slow maybe 2-3 times but now its totall dead and makes a click once every time the key is turned. (click comes from the pass side) The amp meter shows some power and the plugs heat up and the interior light comes on (not sure if that helps) Anyone know what I need to do? New batteries? Thanks.
