1999 Discovery 37V Electrical Issue

[RJPerry]

Helping a buddy with an electrical issue and could use some help! He lost shore power so I traced it from a J-box outside his electrical bay, to a 30amp breaker enclosure at the base of the rear bad. That's where I can't find where it goes from there. I would assume it went to the relay box (shore power/generator power relay) located next to the 120 volt panel mounted low in the kitchen! When gen set is on, relay switches to gen power and panel is powered up. Just can't figure out where it goes from that main breaker to the relay??
Thanks if you can help!

Have you tried getting the electrical drawings from Fleetwood? Email your request with the VIN or FID number.
Yes the 120 vac shore power comes into the T/R switrch first then to the load center (Main AC Box) from there the AC box distributes AC throughout the coach.
Good Luck

Typically genny and shore sources enter the transfer switch -> selected source goes to main breaker -> branch circuits.
