Looking for 1990 Regal SE 33ft wiring diagram
Hi Y'all,

I was wondering if anyone has a copy of the wiring diagram for a Barth 1990 Regal SE 33ft.

We have diagrams of nearly everything, just not this one Wink

The electrical plugs on the passenger side of the RV aren't working. Besides that all other things seem to be working great for as far as we can tell.
(If anyone is great at troubleshooting with that or has encountered a similar issue, happy to take your advice.)

Just not quite sure where to start. Thank you

Thanks!

Whoop. Found them!
I couldn't delete this post for some reason, so just informing you in the comments that I found the diagrams.

Any tips or advice still very welcome though.

The closest thing we have here that I know of is the 1986 GM chassis wiring but it does not show the Barth coach wiring other than headlights, tail lights, etc.

Perhaps a member has an original diagram they got with their coach. I was not so fortunate with either of my Barth coaches. My 1986 33ft tag axle Regal had problems with the side plugs also. Whenever it rained the plugs went dead. Turns out the rain leaked into the plugs and tripped the GFI circuit breaker. The outside plugs are fed from GFI breakers under the foot of the bed. You may have a similar setup, check those breakers.

If you could scan your diagrams and post here it would be great!

Good luck with your coach. Mechanic
