    125m wiring (ignition, elec start and lights)

    ok after getting my 3 wheeler back, i thought i knew what i was doing. well i guess not.
    ok the ignition was yanked and the wiring cut. there is 4 wires, red, green, black and black w/white stripe. all unhooked it starts/runs with pull rope. connect the red and black, starts and runs with pull rope and get a neutral light and head/tail light. same thing with the green connected to the red and black. the black w/white stripe kills the motor when connected. the rest of the wiring is untouched as far as i can tell, just the ignition plug on the harness was cut off.

    question is the green wire, is it for the elec. start? can't get the starter to work. battery checks good when tested, but i have a flickering neutral light and headlight like the battery isn't getting a connection or is dead. i'm wanting to get the starter figured out and not having a constant even light bites riding the tight woods around here at night.

    once i get this figured out i'm gonna stick in a toggle switch for the key ignition so i'm not running the battery down when parked (short term fix till i get the parts together to fix it properly)

    any input is welcome as i don't know what i'm doing it seems.

    well, my buddy's sister has my manual right now. i had asked about this in my stolen/recovery post, so i did look it up on here and printed it out. http://www.3wheelerworld.com/attachm...6&d=1261801363 it shows 4 wires going to the combo switch, so the green wire is the (Dg) and red wire is (Br) then? i'll give it another go in awhile. i can live with the pull start really, but not having consistant lighting

    ok i thought something just didn't seem right. i have a tester, but not a load tester. so this time i had my battery load tested, showed 12v then duiring a 10sec load test it dropped below 8v. so the battery is bad. guess things are on hold till i get a new battery then.

    Jon boy,
    Question for you bud, on your 125m if you donot have a battery installed you can still pull start it right? But will your headlight work if you don't have a battery connected? I HAVE A 125m with no battery & when I pull start it the light doesn't work.

    Thx,
    Glad you have you trike back, just sorry what they did to it.

    yes i can pull start it without the battery and yes the lights work if the Red and Black ignition wires are hooked together.

    thanks and i will say i'm very suprised it wasn't molested or parted out.

    on a side note: helped my brother today empty his trash trailer at the local dump and happened to mention to the guy working there if he sees any 3 wheeler stuff to call me or my brother. next thing he said turned my stomach, they just hauled of a container last Fri. and some guy had just trashed a full 10ft trailer worth of 3 wheeler parts and stuff 2hrs before it was taken away.

    let me look at my ignition switch I just had to re solder all the wires back on to it and everything is working, for some reason I keep thinking that the red and green is on with lights , and the black and black and whit is off on the keyed switch, at least I think that is how mine is ran, like I said I will check.

    cool, thanks. black/white should be the one for the kill switch. green ground. red positive and black looks to be the lights from the diagram i posted above. but in that diagram it shows the green and black/white being connected with ignition off. mine still runs with these two connected and it shouldn't i would think.

    I finally got a chance to take those pics for you so here they are.
    also the way my ignition works is the red and black are the only two that have continuity when the ignition is on, and the green and black and white are the only two when it's off. Good luck hope you get it all working right again.

    maybe the starter solenoid , or there is a fuse as well, which I'm sure you've already checked that but hey what the heck replace it anyways. otherwise I"d say they broke you're keyed ignition.

    dang, the solenoid. that's one thing i had forgotten about. thanks for reminding me muthey.
    guess i better get a good multi-meter and start tearing into it.
    i checked the fuse and it's good. yeah, you could say they broke the keyed ignition for sure since there is nothing there but a hole in the dash now.

    EDIT: still there has to be something else going on. even if the starter solenoid is bad or something, i should still get a neutral dash light and working head/tail light correct? they work when motor is running and i can't see anything wrong with the harness execpt where they had cut out the keyed ignition.

    I'm thinking they busted the contacts in the ignition then. turn it over and you should have continuity from black and red when on, and green and black and white when off
