Battery Short randomly losing ECM power w/ign on

[Gump12b]

Brock, I did the headlight test on the 4 pin connector for the ecm, passed with flying colors. I didn’t get a chance to check the terminating resistors that’s on the agenda for tomorrow. I saw where your ecm was disconnected in that thread. What are the odds this reconditioned ecm is also a fluke? Could my old ecm even have been damaged by the short since the 15a inline fuse from the batteries wasn’t blown? Also I want to make sure that it’s correct without the ignition on that I can power the bulb from both hot lines on the 4 pin.

DVT873, I will also try to follow your suggestions tomorrow. I removed the block fuse as it was partially blown and I thought that was the source of my intermittence. I will check the starter wires and bus fuse connections again. I was very tempted to remove the inline fuses as I saw a few people with similar issues and that seemed to be the cause.

Huge thanks to you all I appreciate your time and suggestions!!
