Anybody have copy of 99' U270 A/C Wiring diagram pages?

Up here in the mountains at Idyllwild in So Cal and ran into an A/C power gremlin. Apparently, the microwave circuit has got a dead short somewhere. It pops the breaker and will make the contractors dance in the ATS if the Microwave circuit breaker doesn't pop. The Inverter control panel (Magnum ARC-50) instantly shows A/C overload when the inverter kicks in after popping the shore power breaker. Pretty sure the wiring must have a short in it somewhere all of the sudden. Anyway, I have misplaced my wiring diagrams for the coach A/C power (along with a bunch of other pages that I placed in a folder to make copies of ::) ). Does anybody happen to have a scan of the relevant pages? IIRC, the microwave is on its own... but I can't say for sure. Tys was in the process of making some apple crisp type stuff, and I had to run an extension cord from a different circuit after jumping through a bunch of hoops to try and figure out what was going on with the A/C power. I sure don't want anything to discourage Tys from making any of her delicious apple crisp type stuff ;D
Thanks!

Don, these are from my 2001 White Book.  It has to be pretty close to yours.  At least maybe a place to start. Hope they help.

Don,

I would start by checking connections at the inverter/charger since the microwave is supplied by an inverter circuit (probably off the sub panel), and if separate ATS for it's output there as well.

You're making me hungry...

As many mods as you've made, I'd be surprised if there is a original wiring circuit LEFT in your coach!

X 2 on checking the inverter sub-panel.  That's the way our our original microwave was powered - separate circuit - and that's the way they (AM Solar) wired our new inverter.

Thanks Roger,
The third sheet confirms that the microwave outlet is on its own on the second breaker of the inverter sub panel. I will start at that panel and work from there. The other two circuits on the inverter sub panel are working fine, so I don't believe that it has anything to do with the inverter wiring. Besides, with thee Magnum Mini panel, I can bypass the inverter and route the shore or generator power directly to the sub panel. I did that initially and the results were the same.
