System monitor issue 1994 Itasca sunrise

[Stella_sunrise]

Water pump doesn’t work, idiot light levels don’t work. Checked fuse, it’s good interior lights all work so I’m assuming batteries are good to go. No power to monitor, range fan or range light. Any thoughts?
Thanks in advance.

Download the Winnebago wiring diagram and it will show you the wire color, plugs, and grounds which should help you troubleshoot the problem.

Most 12v electric issues are ground wire related.. If all those devices are run from the same system monitor, they might be all tied into the same ground, so that's the reason those devices aren't working?

Check the ground wire to the panel and go from there. You'll need a basic multi meter, but also need to know how to use it... You could also use a power prob, but you will also need to know how to use that as well..

Good luck!
