I have a Xantrex TrueCharge 20+/40+ Amp mutistage battery charger that is not showing any indicator lights at any time, whether the engine is running or not. I have a West Marine power switch w/ separate house and engine switch. It also has an emergency cross. The engine meter shows approx. 13 volts. The Xantrex meter at the nav station reads approx 13.5. I switch both house and engine on and have also been switching the emergency cross connect on but still nothing and no indicator lights. Any torubleshooting ideas would be much appreciated. Thanks!
I think you'll find the Xantrex is your 120volt charger. It will only show lights when the boat is connected to shore power.

It appears your house batteries are not in good condition electrically speaking.

Follow Hellosailors advise.
