RE: Battery Short randomly losing ECM power w/ign on
Rawze, thank you for the quick reply. I have done the tap test with a screw driver and mildly with a small hammer to no avail on this “new” reman ecm. I got the ecm straight from Cummins (still haven’t turned in my old one for a core).

Brock, thank you as well, I will have to try your headlight test tomorrow. All of the ground connections are in good shape, including the ones right on the firewall, no resistance in any of the ground wires or in any of the power wires directly related to the ign/ecm. Where did you measure the resistance for the terminating resistors?

I’ve been trying really hard to figure out what could’ve been damaged from the battery shorting out on the battery box/frame.
