2003 Endeavor 40'PST.-triple slide

Having a 12 v issue with our unit. Original owners. A/C/Lights/Water pump etc. all shutting down. Not working. However we are showing battery voltage to the unit. We are looking for wiring diagrams or help from others that have had these kinds of issues. Noticed first time it happened, flushing commode shut down power. Thanks for any help. Have checked breakers--Volt meter showing dead at fusses

You might try flipping on/off the salesman switch. It is basically a large contactor that shuts off all 12 volt power to the coach and is known to failure. Some people bybass due to failure and it is a large parasitic draw on the battery. On my coach it is located in the rear passenger side electrical bay but yours is probably different.

I e-mailed the wiring diagrams again. Did you get them this time?

Sounds like one of your continuous relays may be hanging up, check your rear run bay passenger side as mentioned by jacwjames, should have two.
