just tried to hook up my toad finally to my new to me 98 holiday rambler endeavor. No power to the 7 pin. I have no books on this mh. Haven't looked at the fuse panel yet. Any thoughts on where to start?

Fuse panel....

Dennis4809 · 09-24-2020, 07:06 PM

Fuses! In my case in right rear compartment with a lot of other electrical. Inside a Buseman fuse box.

will look tomorrow. Hoping it is this easy. I have a long horrible history with trailers and lights.

If no power at all, my first place to look would be a disconnected plug at the 7 pin plug, or corroded connector close to the plug. Look at the rear of the 7 pin plug for corrosion.

"No power". Hmmm. Now, are you saying that every single pin in that 7 pin plug, is not functioning as it supposed to? Or, are you saying that, the 12V hot lead, in one of them is not functioning but, all the light signals are? If ALL the PINS don't have any function, first off, that would be rare as, since there's multiple functions, at least one should function. But, stranger things have happened in the RV world.

As Bigd9 stated, I'd begin by looking at the back side of the 7 pin plug and make sure all is well back there. What I mean by that is, make sure all the wires are inserted in the correct ports and, are clean and tight. Then, yep, start searching down each function. Probably start with the regular lights first as that's the easiest circuit to check. Turn signals are a bit harder. But, if your coach is anything like ours, an '04 Itasca Horizon 36GD with the CAT C-7, that 7 pin plug has its own set of fuses.

So, your work is cut out for ya. Please report back on what you find.

Update...Spent some time under the MH today. The loom for the plug was not plugged into the wiring harness. No power issue solved. Unhooked the two connectors for the MH, plugged the two ends of the loom into them and I have power to the 7 pin plug. New problem. Now when I turn on the left turn signal to check it the front left turn signal blinks, the left side marker blinks and the rear RIGHT turn signal blinks. Something is crossed in my connectors. I don't suppose there is a aftermarket harness connector that will fix my problem.

So it isn't just me?

Final update... took mh to shop. Apparently when the motor was replaced they really messed up the wiring harness. All fixed now. At least it wasn't me.

Funny, back 15 years ago when the Cummins ISB engine under warrantee was replaced in my 1997 Discovery, the Cummins shop screwed up exhaust brake wiring, and several bolts holding the engine to the transmission were loose and in one case the bolt was actually missing!

And you wander why I laugh when someone post a comment like "I want a professional to install my xxxxx" If they only knew.

Glad you got it figured out sand everything is working.

And now you know why I do as much of my own work as I can. "Professional" does not mean competent, it just means they get paid.
