  • ok my turn with the pickkup wire problem

    Well Sid, and all that have been helping me through the mongrel/Rusty swap and mix..

    I went on a ride yesterday (first since Deuce)... the rear tire leaks a little, but i'm riding like a granny anyway....

    well about 65 miles and a ferry trip later.. the same problem came up that i had at Deuce... figuring it was carb again like i thought .. (and sid helped)...

    losing one cyl... then gaining it back if i let it drop to about 1500 rpm.. well by the time i stopped fof dinner.. i was only about 65 miles from the ferry back home. and another 15 miles after that..

    wel then i started backfireing, popping, and even at times dying totally.... figuring im not gettting stuck on HWY 101 in the dark, i figured it was the wires in the pickups... (32K on the motor.. never before addressed by my uncle.)... i limped home.. missing 3 ferrys and making the midnight one...
    rolled in the driveway after a lot of nausiating 20-30 mile per hr travel..

    and today pulled the cover.. after reading the info about the "hourglassing effect" of the broken wire..
    one was sooo bad it almost hourglassed just by looking at it.. it was that apparent... .
    the other one looks like it was pinched between the mount and the coil.. (mmm looks like someone broke it up on this side.. then fixed it up..)... also that seal is leakin...

    so atleast i know another thing i can soon check off the list.. as i try to get this thing done..

    When you replace the wires, try to find some VERY supple wire to replace the originals. I used an old lead for a multimeter; this wire is meant to twist and bend. You might be able to find it at an electronics store (not RadioShack!), but if you are stuck, buy some cheap meter leads and cut the required wire out of them. Solder the juctions with the old wires, but don't use shrink wrap as it will not bend properly. Electrical tape works OK but the engine heat makes it lose adhesion. Not sure what the best covering material for the junctions is, but electrical tape will work.

      I re-did mine with test lead, I went all the way back into the harness and soldered new leads and used shrink-wrap. Look at the wires and mounting points carefully. Move the advance full range while you're setting the wires up and 'engineer' the routing so the wires move easily and bend along their whole length, not concentrating any flex in one spot. Use all the wire you need. With some fiddling and adjusting wire lengths, I have mine barely bending at all.

        Recently had to re-wire my pick-up coils for the second time. I used heat-shrink the first time. It was too stiff and the wire broke at the edge of the insulation.

        This time, with suggestions from forum members, I used test lead wire (more flexible) and liquid insulation. The liquid insulation was purchased at a local hardware store. Required several coats and drying time but stays as flexible as the wire.

        I have several hundred miles on the new fix.

        Good luck with your repairs.

        Ride safe!
