Thanks, wil check that out later today. I'll post pics too maybe that will help me. The only question I have really is the first question I posted - about wiring - but with some new developments.
I can't seem to get a spark. But the green wire that comes out of the magneto thing sparks when I hold wire on head & kick it over.
Q: Do I need they yellow wire hooked up at all for bike to run? It's only for lights right?
Q: Where does the green wire go?
Q: What wire can I splice in a kill switch? Regular on/off toggle OK or does it need to be "feed through" switch? (not sure what hat means someone told me that)
One person told me that the ONLY wire I need on bike is the black out of the stator, and to put a kill switch between the stator and the ignition coil. (i assume in-line on this one black wire?)
What about the white wire that goes to coil? (see drawing above)...
THANK YOU!!!1
not 100 percent sure on the 175 but the other Yamaha models use the black/white stripe wire for the ignition.there also should be a diode there to keep the engine from starting up rotating backwards.that diode needs to be there.it hooks up the ignition coil coming from the magneto and you can wire a kill switch to it.run 1 wire from the kill switch to the black/white stripe wire and if it has 2 wires the other wire goes to ground.you can use the factory kill switch which is on the throttle on a Factory throttle.
here is a example. the 1 wire witch goes into the black/white stripe circuit.
all the other wires are for the lighting and battery charge. do you have pictures of the wiring,I would like to see them to make sure.
your bike if it is original there has breaker points and condenser.the CDI on the 175 came out in 1978 to 1981.all earlier models were equiped with breaker points.
