    Ok so determined it's multiple issues found the door jam switch was missing its insulation and rubbing on bare metal causing a relay to click and get hot. Fixed that....

    Then I got the car started and as soon as I shut it off the coil and starter issue started up again. I pulled apart ignition switch wiggled some wires and it stopped doing it. Since it's a 2 piece ignition switch it still requires a key to drive but I should be able to put a switch panel w/push start and fix the issue .

    So about ready to give up on this chassis the electrical problem came back and left me stranded and pushing the car home.


    I've traced it to the obc security box but even with that bypassed it has the issue, if I simply unhook the grn and grn/red box wires all the symptoms go away but then there is no fuel. If I hook them up then it's the tach freaking out, coil firing, starter turning issues again.

    Going to replace ignition switch and hope for the best

    time to chuck that starter motor!

    also why does it sound like a truck? Is that straight out the dump?

    P.S really digging that brown 7!

I've decided on getting an entire parts car for when the time comes to swap as it's hard/expensive to find and buy parts for these e23s

    So discovered the car has been pretty molested in its past life, found all this wire under the rear seat with 99% leading no where and 2 wires tapped into my body harness. This looks like the remnants of an old alarm system and an old stereo system. Car does work now but not sure why as this was all dead weight wiring that was not connected to anything.



    I also sanded, used,
    rust reformer and repainted the battery tray.

    After-

    So car has some sort of electrical issues now... i haven't touched the electrical yet so not sure what has caused this, possibly a mouse or something.

    As soon as the key is put it the car starts reading an rpm signal and the coil starts firing constantly. Sometimes it will very slowly crank over without me turning the key. Car no longer starts, the coil stopped firing for a bit and I got it to almost start but no luck.

    I've been looking into the wiring but haven't found an issue yet, going to pull all the 12v power wires/look into the fuse box and trace them as the starter should not be able to turnover on its own without a signal from ignition switch.

    Almost drivable. Decided to make some videos showing the 7 series and will be doing 7 vs. 7 comparisons. This video is just on the brown e32 as somewhat of an intro for it to my channel.



    Also
    E23 has been started!


    And my brothers e32 is cleaning up very well.
