    Hello,

    1987 K-5 Blazer, my question is about the wiring at the A/C compressor.

    At the point where the wires enter the plastic wiring plug, there is a solid core piece of wire bridging the black wire to the green wire. This doesn't look right to me but I wanted to get advice before I rip that extra wire out. The previous owner had some work done and then complained of blowing fuses every time the compressor tried to engage so he just disconnected the plug.

    My wiring diagrams (Haynes manual) are not detailed enough for me to make a decision.

    Any help is appreciated, thanks.

    Craig

    One green goes to one spade on clutch , one black comes from one clutch spade to ground . Get a new connector from a junkyard or another member .

    Thanks,

    One spade with green wire, check.
    One spade with black wire, check.

    Wire bridging two spades together? Yes or no? Sounds crazy to do that with a ground wire...

    I'd post a pic but I don't have a digital camera...I still like film!

    The single green comes from wiring harness to one spade .

    The black runs from the other spade to ground .

    Nothing bridged .

    the green CANNOT bridge the black , it would pop fuses , it needs to go through the clutch coil first .

    I think what he has on there is something like a diode or some other kind of electronic component, my old car i had, had this bridging the two wires, not sure what it was for, i just disconnented it.

    Yes, it does look like it could be a diode. I'm not an EE so I'm not sure why it would be there.

    I just eliminated mine, worked fine, don't think it's actually a diode, but i believe it has something to do with limiting the current to the compressor, but as i also said, i eliminated mine, worked fine.

    Have fun,,,

    its a diode. its used for spike protection and feedback protection. thay are a 1 way electric valve.
