    Need help with Points wiring on 77 750

    Re-assembling a basket case i recently picked up... 1977 GS750
    I need to verify the points wiring. I have a manual that appears to show the 'white' wire and the yellow condenser wire attached to the 'movable' side of the 1 & 4 contact and the black wire connected to the movable side of the 2&3 contact but the yellow condenser wire is attached to the non-moving side of the contact.

    The points that were in the bike had all the wires to the movable side of the contacts.....

    Can anyone verify this setup?? Does it make sense?

    from the manual:

    First of all, move the spades for the condensors and the black coil wires to the NUT side of the bolt on the points and have one of the insulators between the spade and the metal assembly of the points. This ensures they dont ground out on the points assembly or the timing plate. The bigger plate with the 1 and 4 on the left side sets the timing for cylindes 1 and 2..obviously. The smaller plate is therefore the one for 2 and 3. Set the gap on the points by moving the engine over in a clockwise turn until they open and the little nub that rides on the crank is in the center area of the lobe that opens the ponts. Then loosen the screw and set the gap at approxmately 12 to 14 thousands. Go to BASSCLIFF WEBSITE and youll find a factory service manual there that you can use or download.

    I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

      I stand corrected. I went and snapped a few pics of my 77 and it seems that you can have the coil leads on the head side of the points bolt..heres the pics of how they should go... Notice the insulator between the coil leads and the points assembly body as well. I would think that both can go on the nut side of the bolt as well. Thing is they need to be insulated so they dont ground to the timimg plate thru the points assembly..I think you know what i am trying to say.

          Just be sure theres an imnsulator between the two wires. thing is they cant ground out against each other or the timing plate.
