Shore power issues

[Stanford]

My 2021 R-23 with lithium ion battery upgrade was found to have a dead house bank and fully charged engine and thruster batteries while stored on the trailer and plugged into shore power. I used a outlet tester to confirm proper wiring, and measured voltage on the female end of shore power cable to be 125 V. However, once plugged into the cockpit receptacle and turning on the shore power breaker and switch, the analog voltage meter on salon AC panel reads only 15 V. And then when I switch on the battery charger, the voltage drops to zero and the reversed polarity light comes on. So I have turned everything off and disconnected the shore power. I would appreciate your expertise. Roger Buck, 256-390-3101, rsbuckmd@gmail.com

I sent you an email Roger.

But to start with check the wiring at the charger. For loose connections or wire corrosion.
