The compressor quit coming on. But by moving the wires that go to it it came on then went off again when I let go of the wires. So I pulled all the tape off and exposed the wire and unplugged the compressor. I could find no obvious place where there could be a short. Of course, that when my multi tester decided to stop working. I put everything back as it was. Now neither the compressor or fan comes on. Is there some kind of wire harness I can buy to replace all of the 15 year old wires.
