I’m not sure what electric boxes you are talking about. My front run bay doesn’t have them. Here is a picture of my front electric run bay. Thanks

Thanks for the info. The side lights do work. Not sure about your comment on the two electric boxes? Attached is a picture of my front electric box on driver side. Thanks so much

Merry Christmas to all and thank you for all your advice. 🎄🎄

Thanks Steve for the suggestion. I carry a spare relay and I had a friend help me switch out the relays but we couldn’t find a problem with the relays. All my relays in front electric bay are labeled except one so don’t know what it does. All the relays in the rear electric bay are labeled except one. I wonder why they didn’t label all ??? I will check tge trailer plug. Have a very Metty Christmas 🤶

Thanks Tom for the the download link. I have the original wiring diagram book that came with the coach. My problem is I don’t have the skills to understand the wiring diagram but I have a friend or two that may be able to assist. I will continue to work to find the issue. Thank you so much for your assistance.

Thank Roy, I have checked some of the relays but will continue to check. Another development is that the Fog Lights don’t work? Thanks for any suggestions.

Replaced the headlight switch, but unfortunately that didn’t fix the issue. If I push the ICC switch (think that is what it is called) the marker lights and taillights come on. Could it be the solenoid in the driver side rear run bay ? I replaced the two on the curb side rear run bay and that fixed my 12 volt light problem. Thanks for any suggestions.

Ok thanks so much for the information. I discovered that if I push the smart wheel button above the wiper control that all the marker lights and the taillights come on. So I guess that indicates that the smart wheel control box must be ok. I’m hoping that this means that the light switch is the issue. I will go to Napa and try to get new switch. Thanks to all for assistance!!!

Thanks for the info Stephen. When you removed the switch does it come out the bottom of the dash or did you take it out of the access hole on the dash? Any advice on getting old one out would be much appreciated.

I have been having an issue with my pull out light switch for some time. When I pull it on at times I need to wiggle the pull out stem to get headlights to turn on. I’m wondering if the switch could also be to cause of my lack of taillights and marker lights. I’m thinking I need to replace the pull out switch. Can anyone tell me the part umber and where I can get a new headlight switch? 2003 Dyansty

We stopped at New Hampton, Ia at the TriMark factory and they were very helpful and had what I needed to repair my entry door handle. I first went to the HQ building and they sent me to Service & Replacement Parts. Phone number 800-431-8616. The person I talked with said she needed a photo of inside door mechanism. See attached . It turned out that my part number was 22665-02. Installed the new handle and we are back to not having to crawl in the window after my wife closes the door 😁. It was sure nice to find a Monaco supplier still in business.

Tom I purchased a Roadmaster receiver spare carrier for trip to AK. It worked fine and never needed the spare thank goodness. I’m not going back to Alaska and I know you are a long ways from Cheyenne Wy, but if you were ever passing through this way I would just give you the unit. I would rather have someone getting some good out of it rather than sitting in my barn taking up space.

I’m in Wisconsin and when we head west I’m going to stop in New Hampton, Iowa and take to coach to TriMark and have them help me decide what I need to replace the door handle.

No solution yet.

It did check the wires going into the smart wheel control box and they are good. A number of years ago I replaced the wires going into the smart wheel control box with larger gauge wire as the wires that Monaco used were not large enough to carry the current and they melted the plug. Still don’t have taillights. Still on the road traveling only in day time. When I get home I will figure out what is going on. Thanks

Thanks for your good advice. On TriMark web site they say that 13438-04 is no longer available. RV Parts Center.com say that TriMark 030-1400 is a replacement for the 13438-04 so I will call TriMark next week to see if that new number will fit my door.

My entry door handle has broken. I tried to drill a hole and use a screwdriver to move the lever but I guess it’s so loose it doesn’t work. I am in need of a new outside door handle.TriMark 13438-04 Any suggestions on where I might be able to purchase the tri-Mark replacement handle thanks so much.

Thanks Tom, but the repair was for a fuel leak. A plug had loosened up and was leaking. The repair guy didn’t mess with any wires. I’m wondering if it could be a problem with the ignition switch or the light switch? We put the coach in storage while we home for a few days so I’m where I can’t work on it for a few days.

After a repair we were late leaving and discovered I had no taillights or marker lights. Headlights work, emergency flashers work, turn signals work just no taillights on coach or on toad. Any suggestions? Our coach is a 2003 Monaco Dynasty. Thanks

Pulling into Augusta, MT, we smelled fuel and we were lucky that this happened as we were pulling into town, as the roads were narrow with barely a shoulder. There was a campground at the edge of Augusta in front of which we parked for the day! We found the fuel leak. Fortune led me to call a mobile repair guy in Great Falls MT. Karl’s business is Diesel Fever, phone 406-781-6898 and I recommend him to the sky! It was 6pm when he arrived and by 8 we were back on the road to Helena! I pulled the headlights switch and had headlights, but no taillights or marker lights. Any ideas on getting taillights and marker lights working? Thanks 2003 Monanco Dynasty

I have the same adjustable pressure regulator and I may need to increase the pressure as it is now on 45psi.

Tom I found the problem was in my new whole house charcoal filter was directional and I had put it wrong. It would help if the manufacturer would put an up arrow on the filter. Anyway the charcoal had come out of the filter cartridge and the loose charcoal was stopping the water flow. Think I have it fixed now. Thanks

I didn’t think so but this one sure didn’t work the way I put it in☹️☹️. I will see what the company has to say if I can make contact with them.

They were ifilter. I’m thinking it may have been my error putting the charcoal filter upside down? Don’t think there was any indication on which end was up so not sure. I’m going to contact the company and check with them. Glad it wasn’t a bigger issue.

I found my problem 😁😁. Last winter temp got to -5 and my AquaHot burner stopped working and the original blue filter canisters broke, couldn’t believe it!! I ordered a clear iFilters whole house filter, but it turns out the charcoal filter must not be designed to be moble as I just looked at the filter canisters and the charcoal was 1/2 full of loose charcoal which stopped to flow of water. Took the filter and put in my winterizer bypass pipe and it seems to be good to go😃😃.
