I keep having electricity problems, ECM keeps blowing, headlights stop working. I got it running yesterday and when I tried to turn on the headlights on it cut off and won’t start back up. All fuses are good. Please help.

Good morning,

I would first test the battery and make sure it can handle loads. If the battery is low, it will shut off the engine when the headlight is commanded on.

Do this test and let me know the results. Power is always the first thing we check when in this situation.
