1993 Winnebago Brave no power in home

jlewis50 · 03-24-2015, 07:56 PM

My New to me RV has no power inside the unit. It is a 27ft Winnebago Brave. I can't locate the breakers or fuses for the interior cabin. The batteries are charged, and generator runs, and even on shore power no power inside.
Any ideas?

Check your battery disconnect switch (probably just inside the door)

Here's a copy of the Operator Manual for your coach. I don't know if you have the 27RC or 27RQ, but if your go here Wiring Diagrams you can select the year and model for your coach and get full wiring diagrams.

Btw, here's the 1993 Brave Brochure, just fyi.

Check the transfer switch.

Well a quick update. I was finally able to get power inside with shore power and generator. Still nothing with the batteries. Had batteries load tested me they check out. The batteries do work to power the steps.
I checked the dash lockout switch and it was n the on Position.
Still no lghts in cabin off of batteries. I did find the breakers and all were on, fuses in place and nothing wrong.
I'm thinking the relay to the lockout may be at fault.

The steps should be powered by the chassis battery. The interior lights will be powered by the coach/house batteries.

Well I have checked out everything and I still have no power from the house batteries to the house area. I think a relay may have failed and keeping the circuit closed.
I reviewed the schematic and don't see a manual isolater switch. Anyway, I will take any ideas before taking it to a shop.

The AUX BATT switch on the dash (see page 2-11 of the Operator Manual referenced in earlier posting) disconnects the coach from the house/coach/auxiliary batteries via a solenoid that should be visible in the wiring diagrams. You need to make sure that this switch is ON to have power in the coach.

Appreciate everyone's help with my problem. I found the battery isolater panel up front under the hood. The relays were in a side panel.
There were 2 relays in the panel. Relay one had 12.6 volts on each leg.
Relay 2 not so good. 12 volts on one leg and nothing on the other leg. The interior switch had no impact on the relay.
It is either the relay or the interior switch.
I jumped the relay until I can replace it. I know have power in the coach.
It appears the switch is powered by one leg of the relay.
Fuses were in place.
The connectors were dirty in the unit and I was able to make it open and close with my battery charger. Hopefully this will be a temp fix.
The relay is $55 on eBay. Wonder what the stealership gets for it?

Appreciated everyone help.
