I wonder if anyone else has had trouble with their "tow board?"
It controls the electrical towing circuit to a towed vehicle, and isolates the coach electrical system from the towing circuit. On my 04 Allure Seaside it is located in the service bay which is the last bay on the rt side where the fuel filters are. It is mounted in the ceiling of the bay protected by a removable black metal plate that screws into the ceiling of the compartment. It is an electronic board with a 7.5 amp fuse for each of the towing circuits, i.e., rt turn, left turn, brake, marker lights.
In my case I keep blowing the fuse for the rt turn and brake light.
Disconnected the coach lights work fine, AND so do the tow vehicle lights.
My 12 V electrical skills are basic, but I'm thinking about trying to hook up an ohm meter between the effected circuit on the tow plug of the coach and the corresponding fuse in the tow board to see if the resistance is higher than the other circuits. By doing that I would hope to find that the wiring between those two points is shorted and maybe just replace the whole wire.
On the towed vehicle I might try doing the same between the tow plug on the car and the point where the tow wiring connects into the tail lights. However, there is a diode in that circuit that keeps power from vehicle applied braking from sending power back to the coach. I wonder if that would defeat an ohm test?
Am I on the right track? Has anyone else had a problem like this?

George, I think that you have a dead short on the right turn signal in your umbilical. With no lights or turnsignals on I would check for continuity between each post on your coach plug a ground location nearby. I doubt this is where the short is.
Next, plug your umbilical into you coach and check for a short the same way on the car end of the unbilical.
Lastly, if no short found before, plug the car end in and check the connections on the car female as before. I suspect that this is where you'll find your short.
I had this same problem early on with my seaside. Good luck.

George,
I've had a similar problem. Check the connectors on the cable between the coach and the toad. In my case, the set screw for one of the wires had backed out and was shorting against the metal housing of the connector. I put loktight on all the screws, re-tightened and have had no further problems.

Take a small screwdriver, and slightly pry open all male connectors on the tail/brake light connections. In 20 years this is the problem I have ever had with these systems. Of course a good contact cleaner is good every now and then.

Doug,
Thanks. I can see how that would cause a short but have never thought of that. Will check that as I look for the short using the method George Sanders suggested.
Thanks again.

I had the same problem this past summer. I kept blowing left turn signal fuses. After much diagnosis and trouble, I checked the towing cable between the coach and the car. One of the wires had pulled loose and was causing a short.
