Wiring

I have a 1991 American Eagle (class A) motorcoach. Never have had any issue with the 12 volt light system (front inside lights, interior runway lights, porch light. Just were working and go to turn them on today and nothing. Checked fuses and all are good. Does anyone know or can maybe suggest where to start to chase this down?

Try moving wiggling the fuses & connection....corrosion/dirt may have gotten into things.

Battery disconnect switch got moved to Off position?

If it is the switch..... those are the best kind of fixes

What is the house battery voltage reading at the battery posts. If less than 11.7 dcv then charge the battery so it has 12.6 volts.

Is the battery switch on?

Do the 12v lights work when shore power or generator provide 110vac?

If not, then there may be one or two high amp fuses between the house battery and the inverter or converter that has failed.

My inline fuses are 300A Class T fuses.
