It had a gps attached to a relay but that was it. It was on its own dedicated relay.

just a thought...
Make sure the J1939 netowrk for the vehicle (and also the #2 network for the engine) shows 60-ohms with everything shut off for more than 2 minutes.

Checked the voltage, pin an and c only shows .7-.9v and fluctuate. Pin A and D show a steady 2.54

Your not checking for voltages.. your need to check for proper RESISTANCE/OHMS once everything switched off for a few minutes.

I’m not sure how to check for ohms, never done it before.
