Please try with a trusted sidecar, and can you give details on what the direction of the relay was?
direction was forward, and it had a green light. I'll need to check what happens to reversed values tomorrow though. I'll also try with another spare DSC.
When not rebooting, things work normally

No, Its wired -batt => -v spike -m => motor => +m spike +v => +batt
