Thanks for the interest in helping a newbie. Michael thanks for the owners manual link. The system overview helps me build the system in my mind. Just wondered if a relay, contractor, fuse or isolation switch might be at issue. Any knowledge of what is powered off each leg(L-1. L-2)? Hopefully this will all be moot if the seller/broker has it all fixed prior to pickup.
I do have a background in auto mechanics/machinist and aviation electronics so feel quite capable of maintaining most anything. I just need the proper information in order to diagnose. Thank you all
