    2005 bought it not running needed new 12v and wouldn’t start (bad traction pack, swapped for a good used one) starts and runs great now...EXCEPT... the CM is not powering on, at all. Pulled the dash apart swapped the CM out, no luck, spoke with Matt at Texas Hybrid Batteries (super helpful awesome customer service) he sent me the wiring schematic and when I checked the harness voltage there isn’t any, there’s supposed to be 12v to one but I’m not getting anything. Checked the dome and gage fuses they’re fine. Searched the threads didn’t see this particular problem, any hints?

    You are probably going to need to do a good old fashioned trace of the 12 V wire back to the fuse, so the electrical wiring diagram might be useful if the wiring diagram you got from Matt does not cover it.

    For the sake of clarity, did you check the fuses with an ohmmeter for continuity and also that there was power at the fuse?
