I have a problem starting the engine when it is at operating temperature. It starts fine when cold. After the engine cools it will start again. I traced the problem to the glow plug controller. It will not turn on the glow plugs when the engine is hot. Does anyone have an idea on how to overide the glow plug controller? I have tried to force the input to 12 volts and this won't do it. I think it has something to do with the glow plug voltage sense lead. Any help would be appreciated. Thank you Bob P.S. I tried a new controller and it does the same thing.
