Howdy Dom, and welcome to the forum,Sounds like you have an interesting project--hope you can share some with us after the issue is resolved. How long has your project been in operation? How long was the 12V disconnected before this last connection incident occurred?Possibly related thread:https://myimiev.com/forum/viewtopic.php?p=45544#p45544CMU board thread:https://myimiev.com/forum/viewtopic.php?p=39002#p39002Power supply schematic:The power supply section schematic shows there are 5V low voltage supplies on both sides of a 4mm High Voltage isolation gap--one is isolated toward the 4 or 8 cells of that particular module and is called the "LV" supply and ground; the other is exposed toward the rest of the pack and called the "HV" supply and ground. These are merely names that i created to reference the supplies based upon their location.The cell autonumbering wires and CAN are on this schematic:i don't see any connection to a 12V voltage on the CAN buss from the module side so i suspect it might be on the interface board that you built and are using. If you want to post up a schematic then the guys here would take a look and give you some helpful advice.

Power supply schematic:
