i have a 77 cobra II that we have been working on for some time now... it seems to run really good but i was wondering if anyone knows where to get a decent decipherable electrical diagram... the car wont charge... and since it was in a fire the wires have been mostly guess work. thanks in advance.

think i can help cuz i had the same thing drive me nuts for a
year..... on the back of the heater blower switch there a 3-4 prong
connector.....it had two brown?? wires coming from it and they had
overheated and it wouldnt work. they looked fine but wouldnt blow
air. i fixed it by putting a permenant jumper wire between the two
brown??? wires and its been fine ever since.
to trace it to there start at the pass. side of the car and pull out
the place where the harness connects to the motor..
pull that connector and put 12vdc direct to the motor to see if its
any good....
turns on fine, if not replace it.
if not check that connector i talkd about earlier but bypassing the
switch to see if you can get it to turn. if so then thats your
problem.
hoep it helps

I'm working on trying to figure out this problem right now. But something is confusing me. First of all, I pulled the connector at the blower motor and applied 12v pos. current to the four little prongs that go into the connector. Got Nothing. Out of curiousity i applied 12v pos. to the actual connector and found that by touching one of the wires, the blower motor comes on. Next thing, leaving the blower motor connector disconnected, I also disconnected the connector that attaches to the heater control assembly switch underneath the dash on the drivers side. I then applied 12v pos. current to each of the four prongs. Once again, got nothing. I then applied the current to the connector wires. By touching one of those, I again got the blower motor to come on but only while the fan speed selector was on high. If i moved it to any position lower than "high", the blower motor shut off. Apparently, there are two seperate sources of current going to the blower motor, but I'm not sure why. Also, on the connector that connects to the heater control assembly, the connector was partially melted. I'm not sure if i have the same problem you had or not, but I don't think I do, since i can put current to the melted connector spot and the blower motor comes on. If anybody has any suggestions, they would be greatly appreciated. It sure is cold. thanx

well I am in the process of buying a house. When I get the house I am going to rewire my entire II, I will make a schematic and a wiring diagram with pinouts at that time. Stay tuned
