Wires burned in RV fire. Wires are good about one foot from unit. One wiring harness with six wires, green, black, white, purple, yellow, red. I need a diagram for wiring and am going back with a hunter thermostat that will handle both heat and air.
Motor1258, Thanks for the response, to be more specific, the nine pin connector was damaged, but I was able to connect the wires back to main unit panel. I am ready to hook to the hunter thermostat and do not know which wires to connect to. This is my problem and I do not want to short something out. Hope this helps, I want to get it installed again. Thanks again for caring....Jerry

That is a really bad experience to have had happen. Serious sympathies to you.
I'm hoping/assuming that the fire did not destroy the entire unit and perhaps was restricted to electrical components.
I've a couple of suggestions that may be helpful.
First, I'd see if I could find a Haynes manual for the vehicle.
If I were to be faced with your situation I would probably sip a beer and ponder the engine compartment for a while. I'd try to determine if major components had been damaged, and then replace any that had been overcooked.
Most wiring harnesses have plug connections and I would try to get as complete a harness as possible from an auto salvage company.
Then, as each component was replaced or confirmed undamaged, I would try to splice or plug in the appropriate section of harness.

Either the power supply wiring is too long - i.e. a 150 foot extension cord used to power it with poor plug blades?
Or the capacitor is shot, (more likely)
Disconnect Power supply, wait 5 minutes, try to start the unit WITH POWER DISCONNECTED. (will drain capacitor).
Short capacitor with well insulated screwdriver, get the new capacitor replaced on ebay or local electrical supply or appliance store (not home depot)
Well, it sounds as if you have a Coleman rooftop unit. If you have a start capacitor with a PTCR (Postive Temperature Coefficient Resistor) then it is different than if you have a Potential Motor Starting Relay. Why are you replacing the run and the fan capacitor?
Here is a link to the documentation that you need. If you do not have a Coleman and it is in fact a Duo-Therm, let me know the model number and I will be able to pull up the wiring schematic.
If you google Coleman rooftop air conditioners on your computer, it will give you some dealers that sell that air conditioner and they should be able to help you or tell you where you can get the help.
