I need help finding a replacement or repair source for the "RV Custom Products" 12V Power Distribution Center in my 99 Tradewinds.
Thanks, Vern

Any part numbers on the center , if you can't find a P/N maybe post a picture, more people may be able to tell you if their coaches use the same part.

Maybe this will help.....

Thought I would pass on what I found in troubleshooting the 12V Power Distribution Center on my '04 National Dolphin 5320. Mine uses the board #129757.

Problem:
- Coach batteries not being charged by alternator.
- Chassis battery not being charged by house battery charger.
- Can't hear soleniod operating

Diagnosis:
- Confirmed F32 3A fuse was good, replacing fuse operated the Interconnect Solenoid (loud clunk). Therefore solenoid was activated already but not passing current between batteries.
- Confirmed there was battery voltage on solenoid small terminals.
- Measured across the solenoid large terminals - 1.3V drop across contacts; this should be near 0 Volts.
- Tapped the solenoid case sharply and measured again, now .2 Volt drop.
- Confirmed chassis battery is now being charged by battery charger.

Fix:
Contacts inside solenoid are bad. Replace with Napa ECH ST85 or equivalent CONTINUOUS DUTY solenoid. (disconnect house and chassis batteries before attempting this)

It isn't always the control board.
