    Thanks in advance.
    My '64 G10 only runs with switch in start position,I'm thinking starter switch.
    If anyone has any input or guidance that would great.
    Thanks again.

    The run wire is not sending current from the ignition switch through the ballast resistor to the positive terminal on the coil. The Yellow wire on the starter solenoid is the START wire,,,,,,is the RUN wire on that R terminal of the solenoid still there?

    I dont know,I dont have a schematic to verify wirring.
    The van was running fine untill I stalled it.
    Then on restart It would fire/run on start position.
    The Yellow wire is paired with, I believe black on the starter.
    It appears the yellow from the starter feeds the coil.
    The van had a bad fuel pump when I bought it,so I havent really run it much.


    I Did not spend much time looking at it tonight.
    would you know where I could get a schematic?
    Thanks

    The idea is,,,,,you turn the key on,,,,,it sends 12 volts through the Pink wire into that connector by the side of the carb,,,,,coming out of that connector, it turns into a White/Orange/Purple wire, (which is a resistance wire to cut the voltage down to around 6 volts) and hooks to the terminal on the solenoid that has the yellow wire to the coil on it. So did you mess with any of that wiring? Just start checking,,,,,,see if you got 12 volts on the pink wire going INTO that connector with the key on. then trace it down to the solenoid. The wire could also go right to the Positive side of the coil or someone could of put in a ballast resistor to fix bad wiring. And make sure the points are set right! Even take a test light and test for voltage at the Positive side of the coil with the key on,,,,,wiggle wires if the light won't come on,,,,,

    Here would be the mid point of the circuit,,,,,,,,see if you got 12 volts coming in on the pink wire and see if that 12 volts is getting through the connector into the cloth covered wire and turning into 6 volts when it connects to the R terminal on the starter solenoid. That yellow wire on the solenoid has 2 jobs,,,,,send the 6 volts from the cloth resistance wire up to the positive side of the coil or send 12 volts from the starter solenoid up there only when the starter cranks.

    Donni is correct - balast resistor is BAD! Get a new one & install - it will run fine .

    NEW,when the van cools down it starts and runs fine.
    after running for 15 muiutes and I shut it down,or stall it it only fires on the start side?I also noticed a slight misfire when hot,cold its smooth as silk.
    I have 12 volts at purple on starter,key on not running.
    Does that mean someone removed the ballast resistor and my condenser is getting hot and shutting down?
    Thank You,
    Late model Bikes are my gig,old vehicles Im learning.

    The points need to be closed at the time you check for voltage, otherwise it will read 12,,,,,The voltage at the positive side of the coil will jump from 6-12 depending on what the points are doing,,,,so check it with the engine running,,,,,you got a lot of variables to check if the engine won't start AFTER it gets hot,,,,,,you could have the engine flooded out,,,,,,is there a lot of gas when you look down the carb after it gets hot? Something could be wrong in the distributor or the wiring AFTER it gets hot,,,,,,,Is the points and condenser new and ADJUSTED correctly? You can test for spark after it is hot by taking the distributor cap off, turning the engine over to where the points are closed,,,,,,holding the coil wire close to ground and everytime you open the points by hand, spark should jump out the coil through the wire and to ground,,,,,,

    Huh,I got it.....I believe.
    An internal break in the coil wire .
    I tried a known good one and it fired up.
    Warmed it up,short drive,more idle time,shut it down and it restarted easily.
    Did two heat cycles,both times it went well.
    Also the slight skip is gone
    Thanks to all for your help.
