Technical Support / No power for brake lights at coach 7 pin connector
« Last post by Richard Shrode on July 28, 2026, 04:38:02 AM »A bit of a Hail Mary since we’re traveling and am hoping for an easy fix or place to start looking. Our 2007 beaver contessa doesn’t have power for toad brake lights. Both turn signals work fine but when the brakes are applied in the coach … nothing. Plugged the toad into another rig and it had turn signals and brake lights but when plugged into our coach just turn signals, no brake lights. Plugged a tester into coach and same thing, turn signals, no brake lights.
Going to see if there’s someone in town to look at it tomorrow, but in the mean time, any suggestions of things to check?
Thank you

The door lock is made by Trimark. The "F" code is identified as a pass key that sales personal would have on their key ring to access any coach with the F on the lock. For more information contact Trimark 800-431-8616. Fred

Technical Support / 2004 Patriot Thunder Entry Door Questions
« Last post by Bill Borden on July 27, 2026, 07:07:13 PM »Well we just bought our 3rd Beaver, our 2000 is up for sale.
We bought a 2003 last fall, then a tree fell on it and the insurance company finally decided to totaled it. Very disappointing.
We found a 2004 Patriot Thunder, just 22 miles away.
We bought Alan & Carol Scott's coach. We were lucky to find them.
So on to the door problem, no key for the handle lock. The door was made by Monaco. Roadmaster chassis.
The handle/latch key tumbler has a F code. The basement doors tumblers, have a 211 code.
I have been told it that the F code means it is random key, somewhere between 201 to 250.
Does anybody what key code is for a 2004? I have already talked to BCS, Mike didn't know.
Any help would be great, thanks.
Safe travels,

And be sure you replace the diode with its gray stripe on your left, as David previously mentioned.

« Last post by Brian Fahlgren on July 25, 2026, 09:39:35 PM »The break was in the large black wire plug in the exterior wiring compartment. I'm not a fan of taking old plastic electrical plugs apart; I don't have any other issues with the other circuits in that plug. I ran a short jumper around the plug for the 227 ING PW Driving lights. Thanks again

The 2000 Marquis should be wired the same as the 2003 Patriot as very few changes were made until Monaco implemented the Roadmaster wiring. Using the 03 Patriot wiring diagrams in Coach Assist;
CB28 provides the driving light power and feeds C4-4 (sheet 33)
C-4-4 feeds C24-1, circuit 227, (sheet 19)
C24-1 feeds the Driving lights switch connector. circuit 227 (Sheet 14)
Output of the switch connector runs to the Driving lights C24-2, circuit 228. (Sheet 14)
This would seem to indicate your problem is either a broken wire or a bad connector pin connection in C4, C24 or the Driving Light switch connector. The wires have the circuit #s printed on them.

Technical Support / No power to driving light switch 2000 Beaver Sea Ciff
« Last post by Brian Fahlgren on July 25, 2026, 12:33:56 AM »I recently purchased a really nice 2000 Beaver. I'm going over some things before we take it out for the 1st trip. I recently did the dim headlight fix with added relays. The next issue, my driving lights do not have power to the switch. There is power to the wire out of the breaker that goes to the switch. I can't imagine there's a break in the wire, and I don't believe there's a fuse. I could run a new wire from the breaker to the switch. Am I missing something? The key switch is turned to run. Thought maybe there was a relay that switches the driving off with the hi beams, but it doesn't matter if the hi beams are on or off, headlights on or off. Can't get power to the switch with any combination. I haven't been successful trying to find a wiring diagrams. Any suggestions would be appreciated. THANKS
