1975 27ft Overlander

HELP NEEDED: I am in the process of restoring a 1975 27ft Overlander...I need the wiring diagram for the Control Panel to include the panel connector...I have upgraded the power converter to include a new circuit panel...the original control panel was damaged due to overheating from the stove (that was what I was told)...I replaced with a salvaged control panel that was advertised to be "OK"...nothing on the panel seems to work, water pump, etc...checking the plug I note power on the red and brown lead'in wires on the plug...interior lights, exhaust fan works as normal...

At this moment I am stumped !

Cheers/John

Hello from Colorado: Nice to meet another 70s Overlander owner. I too have a 75 Overlander. I've owned it for two years and have done a lot of work on it. I believe it is now "travel ready" and significantly renovated. My blood, sweat and tears "project thread" is linked below. I have made my maiden voyage in the Overlander and all went darn well.

I have a service manual in my shop and I will shoot a picture of the wiring diagram for the "control panel" for you tomorrow. I elected not to restore my old control panel as I have replaced both black and grey water tanks and I'm using a SeeLevel instrument now instead of the old control panel. The resistive sensors molded into the old waste water tanks are not that reliable in my view. There was 4 wires from each tank all tied into the analog gages on the control panel. A lot of wires for a little information on tank levels. None of them worked when I bought the trailer. The plastic cover was quite yellowed on my control panel. But I did keep the thing in my trailer adding a bit of old vintage look. I use the water pump switch, and I use the range hood opening lever.

More coming tomorrow...

Well, I have 8 pictures of the 8 pages in the service manual concerning the control center. The pictures are downsized automatically when uploaded to the Forums. Let's see if you can enlarge them and mouse around to get the information you need.

Let me know if these photos don't work for you. Then we will try something else.

You know, I did find the control panel well built and the gages used to be of high quality. It's just that moisture and old age take their toll. The SeeLevel is an excellent instrument, easy to install, and quite reliable. That is the route I went. Happy to hear you gain at least some function out of the control panel.

The air conditioner manufacturer may still be around. RV repair shops may also be able to help. A RV air conditioner is almost a throw away item. It quits, and a replacement unit isn't that much more than a new compressor. Some shop may have one they would be willing to part out.
