Two things... if you are still under warranty, let the dealer fix it and document it well so that if your warranty period runs out, you can still get Jayco to stand behind you. The other thing you might do (if you haven't already) is to email Jayco at firstname.lastname@example.org
and request a set of electrical prints for your unit. I know they send them for the TT's so if they're available for your MH, I don't see why they wouldn't send them too.
