OK, How is this for a problem. My ProHeat came on the other night to re-charge the batteries. I was not in my truck at the time. It blew a cork and I found oil EVERYWHERE on the unit and my parking spot at the house. The engine did shut down and there is no sign of a spontanious dis-asembly. I looked it over and could not see anything loose, then again, there was a lot of oil so I could have miseed something. Anyone ever have this problem with your boat anchor, er, ProHeat? If so, what was it? I have to get in in the shop as soon as I am home next time. Back to the old idling game. Layoutshooter
