Time to get the volt meter out. Start at the battery and keep checking along the circuit until you find no voltage.

Don't have power with the engine running.

I agree with Twinboat, more than likely your battery disconnect relay. Depending on the exact model relay your coach uses you may be able to disassemble it, sand the contacts and reassemble the solenoid. Its a very simple procedure and only takes about 5 minutes once you remove the relay from the coach.

Over the years Ive had to sand the contacts on the Battery Disconnect Relays on both of my current motorhomes. Its a simple job and you can get many more years of service from the relay.

If your Southwind is the same vintage as mine, you probably have a "RV Custom Products" Battery Control Center. If you can hear the solenoids connecting and disconnecting when you press the switch, there are two possibilities:

1) In the bottom left side of the BCC are two small circuit breakers, press the reset buttons on these to reset them.

2) There are two battery disconnect solenoids inside. These are magnet based, i.e. in the "USE" position, a strong magnet holds the contacts in. On mine, the contacts were intermittent and the center plunger would occasionally just drop out by itself.

I disassembled the solenoid and cleaned the center plunger and the sleeve it slides in to. I also compressed the outer spring a little so it put a little less pressure in the contacts when the solenoid was pulled in.

Note that the contact are part of the connector bolts. The contacts can get twisted a little when tightening up the connector nuts. Realign these so the large contact washer makes good contact.

Scroll down to the bottom of this link, there are a lot of photos on how I disassembled by BCC. WARNING - disconnect the coach and chassis batteries, and make sure shore power is disconnected before disassembling the BCC

If you have the intellect battery disconnect The chew resettable breakers on the bottom of the Black box in front of the motor you need to check for power on both sides of those because the power flows through those from the engine and from your battery disconnect if you don't have power on either on those breakers then you start working backwards

Well, not much is going to happen today as its snowing and blowing out there.

Got it! Thanks to all who have given me input over the last few days. It was the coach disconnect relay and thanks to Waiter21 I knew how to fix it. Happy days here in Colorado.
