    I searched the past entries back to page 131 from today and search was no go and I do not see it
    Would some have the technical manual answers for me.
    My new to me 2A has a start issue. The wiring diagram is no help because the starter itself has no solenoid attached to it. WTF?
    I have a rod in the face of the dashboard to push. I don't understand a mechanical starter system. Photos and diagrams please to study to figure this out

    Post up some pictures and maybe someone can chime in on whats going on. The rod is taking the place of the relay/solinoid to engage the starter motor. I think it is what is closing the contacts. You might start with making sure your grounds are secure and clean. Thats always the best place to start.

    Yep, just a mechanical linkage to contacts-no solenoid. Check the linkage and if that appears to be working correctly, remove the contact switch from the top of the starter. You may be able to disassemble and clean up the contacts. It would be worth a search on the 2A Page site.

    FWIW the mechanical linkage is a plus because you can test the starter without turning the ignition switch on, thus it won't start. :) I always thought they had a plunger mounted on the firewall that activated the starter, that's what my M series have.
     
  5. yup it only needs a solenoid if it starts by turning the key to the far right. if its foot start or starts by that lever you say you have then it wont need a solenoid. what is your starter doing that's wrong? one of us may have been there before and can help maybe

    It is sparking at the switch and smelled like burnt wire. Remember that the wire IS cloth covered OEM
     
  7. If it's sparking at the switch that is mounted on the starter then it's probably an internal problem with the switch and it's probably grounding out when it's being pushed like an internal insulation is worn out. Personally I don't think you would have much luck replacing that mechanical switch unless you can find nos maybe military one. You might be better off changing to either a solenoid and key start or on off ignition switch and foot push electrical button with the 3 piece large gauge positive battery wire.
     
  8. Also if your cloth covered original wire is as bad as mine was. Your best off to replace the wires.

    Normal wire would work fine from the parts store. I bought a perfect reproduction of cloth covered vynil wire harness from walcks4wd.Com for my cj2a and I loved it.

    Sparking?? Nothing to do with wiring.

    Never had a CJ2 but IF this is like early CJ5 and Willy's pickups, etc, the mechanical "throw-out" linkage and the switch button need to be adjusted to work in sync.

    i.e. the pinion gear should engage and the switch make full contact at the same time. The switch button is adjustable by screwing it up or down on it's shaft.
    Sounds to me like you need to give it a few turns "up." http://www.thecj2apage.com/forums/uploads/4132/46Cj2a_Starter.jpg

    Also the internal switch parts may be worn, burnt, or dirty. I have dismantled them and gotten a few more years out of them by tinkering, such as reversing the contact bar.

    Although it is a common part and can be found NOS.

    My solution will be to replace the starter with a reduced gear starter that is already 12 volt, and wire it with a key like a cj5 . Flywheel tooth count matters here and I have not done it yet. Kaiser willy's offers the solution here with all tooth count options available. The replacement will bolt in WITHOUT any modifications to the bellhousing. I will be adding a key starter switch hidden under the dash so the key face does not show.

    I have a 3a that had this same starter in it, the linkage got worn after so many years so was a real pain trying to get it in right. I went with a 12 volt gear reduction starter, this kinda an odd ball starter so make sure you get the right one. Now it starts with the key switch
    On my 2A, I also changed to an 12 volt gear reduction starter, but kept the button in side to start it, to kinda keep it more original, so now I have to turn the key and put my foot on the button and wow
