So having a diesel I know you have to plug them in when its cold but I have mine plugged in and when I go to start it, it cranks over once and battery goes dead so I jump started it and got it running, ran it a full day and now this morning I goto start it same problem no power from battery. So is this just a bad battery problem or does the engine block heater have a problem in this too?
