    Tricky Yamaha C85 Electrical Problem - 1 cyl OOS - Problem Rolls with Stator wires but new stator - Same issue

    It's quite simple. you have three phases from the coil that charge three CDI position, you can switch them around if you keep the phase sequence the same. The CDI doesnt care where it gets power. Some CDIs calculate phase angle from other inputs to the CDI, that is why I kept the sequence the...

    Tricky Yamaha C85 Electrical Problem - 1 cyl OOS - Problem Rolls with Stator wires but new stator - Same issue

    Update: I used a DVA and tested all components. Now when I say volts,all the outputs of the stator are AC voltage but the DVA converts to a stable and readable DC value. ( to all who may not be familiar with a DVA and its function) . For the purpose of this post. I will simply refer to volts but...

    Tricky Yamaha C85 Electrical Problem - 1 cyl OOS - Problem Rolls with Stator wires but new stator - Same issue

    Boscoe , I wonder what would happen if I fed #1(brown) and #3(red) stator position on the CDI from the working red wire? Basically split the output from the red stator wire and run to the #1 and #3 pos on the CDI. The trigger appears to be working fine. If the current is high enough, the caps in...

    First off, I'd like to say thanks. You guys put in some time and thought into this so far and that is the most valuable resource we have. To clarify, I have attached a few pictures of the stator and the pulser coil as well as the repair manual blurb about the unique dual firing from a single...

    Tricky Yamaha C85 Electrical Problem - 1 cyl OOS - Problem Rolls with Stator wires but new stator - Same issue

    Yes, stator has 5 wires total .Two wires that run to the rectifier for the charge coil. The lighting coil on the stator has three wires(Brown,Red,Blue)that run down to the CDI and feed through to each each cylinders coil pack. When I roll the phases going into the CDI and move it to...

    Tricky Yamaha C85 Electrical Problem - 1 cyl OOS - Problem Rolls with Stator wires but new stator - Same issue

    99Yam40 thank you for your quick reply, and your insight. I tested the spark in using a timing light. When I roll the phases (3 phase) on the stator the problem follows. To me this indicates the signal is properly delivered across the CDI. I performed static measurements across the stator and...
