I was working on my C-10 and left the key on for a couple of weeks. When I went to start it I realized what I had done. I put the charger on it and let it charge for a couple of days. When I went and tried to start it it wouldn't do anything. It had power to everything else but would not turn over. The weather got bad so had to stop working on it. I'm just wondering first, what is wrong, then what would have happened when the glow plugs kept cycling. The batteries were brand new, so I'm worried about about them also. Does anyone have any ideas where to start? Any help is appreciated. RudyJ
