Wraith 35F solar panel

[Bloose]

I have a Wraith 35F. The solar controller shows that there is no input from the panel. I checked the back of the controller and sure enough, nothing. I went up on the roof and the panel has output. That means somewhere between the panel and the controller there is a problem. I cannot find an inline fuse in any of the wiring I can access. I've looked in the cavity above the microwave and behind the drawers in the lower lower cabinets. I have also checked the electrical compartment above the house batteries. I did find the fuse from the house battery to the controller (or controller to house batteries), but, nothing between the panel gland and the controller. I don't know if there is a fuse or what.

Does anyone know where or how to find it or if there is one?

Thanks,
Bloose

Is there a connection at the roof where the wires feed down behind the microwave? I assume you pulled it apart to measure output of the panel but that does not mean it is going into the wire down to the controller.

On the roof is there an mc-4 fuse holder and fuse?

There is a gland on the roof that the solar panel leads plug in to. There is no easy way to remove it or open it from on top. It is sealed with Dicor or a similar product. From the inside there is a hole about the microwave cabinet with wiring for I believe the AC unit and also the solar panel leads. It is not near enough to the gland it get any look at it.

I may have to break down and work at the sealant until I can remove the gland from on top of the roof. Then I can fix or replace it and at least know I have continuity to wires that would go to at least to the cavity (cabinet) above the microwave.

The gland on the roof looks similar to this.

I don't believe there is but I will double check.

Well, if the power is going in and not coming out......

I found the problem.

I removed the solar panel plug gland on the roof and found that it was never connected to anything from the factory. There are wires to the panel input on the controller but I have no idea where they go to.

It also turns out that where the wires from the gland go through the roof and into the coach is above the refrigerator. There is no direct access which is why I didnt see the unconnected wires in the compartment above the microwave. I was able to feed a stiff wire through the hole in the roof and fish it through the hole in the panel between the cavity above the refer and the compartment above the microwave. I then attached some wires to it and pulled them into the compartment above the microwave.

Now I need to figure out exactly where the wires at the solar controller go off to. It would be nice if they went up the the compartment above the microwave but I haven't seen them yet and I dont know if I'll be that lucky.

What really kind of upsets me is that the dealer that inspected it when new never found this and neither did the dealer I bought it from used. Well, the dealer I bought it from may have known and didn’t disclose it. Maybe, maybe not. Either way, it is pretty disappointing all around.
