    Re: No electrical power help

    What transmission do you have in there now?

    I recall you wanting to convert from manual to DOA…I mean AOD.😁

    And you didn’t have a neutral safety on the manual?

    Battery can register 12 volts but still nothaveenough current to do anything.  If it was working when you used it recently, suspect battery

    Re: No electrical power help

    Ok
    Sal suggested the plug for the front harness where it comes through the firewall. Probably a good place to start.

    Re: No electrical power help

    Clean up the connectors on the plug that Sal mentioned, and also the other end of the black/yellow wire at the solenoid. It's the main power supply to the car.

    Re: No electrical power help

    Firewall connector is a good place to start. As you indicated that nothing is working, I’d suspect the power from the battery to the fuse panel, ignition and light switches all come via the Black-Yellow (#37) wire connecting the battery terminal on the starter solenoid.  This wire is thicker than most of the other wires and is in the firewall connector Sal indicated.  Check this wire’s connection at the starter solenoid, and there is one splice in the engine compartment that connects to the alternator’s “bat” terminal.
