TV Backup Lights are on when Generator is Running
Noticed this the other day - when I am parked with the 7-pin trailer plug connected to my GMC Sierra and the on-board generator running on the trailer, my truck's backup lights are on... I know the easy answer is to disconnect the trailer wire whenever I run the generator but I'm curious if this is normal and if not, what the issue may be. Both truck and trailer are new...
Just me, my girlfriend and our crazy Boxer Stella.
