I got a mr heater 175000 btu diesel heater that i thought the electric motor was bad in so i replaced it with a brand new power pack so new motor and vacuum pump. Nothing happens now when i plug it it and the trouble light blinks 2 times (system lockout sparks calling for flame but no or slow motor operation) or blinks 3 times (system lockout no spark). Anyone have any idea what is wrong with this thing? The guy i got it from had worked on it and after alot of hunting online i finally found the correct wiring diagram and he had it wired wrong so i fixed that and still no change so could that have fried the controller? Does anyone no how to test the control box?
