While looking into this, I've seen .05Vac about as often as I've seen .5Vac as the minimum useful output from the trigger coil. Knowing now that it's .5, I'd say the trigger coil is bad.
I've ordered another and will post again once it arrives and I get it installed. Meanwhile, a musical interlude... |

The new trigger coil arrived Friday and I installed it that evening. At first it did produce a spark and would run a bit with some starting fluid, but then I decided that since it had been sitting a while and I had a carb rebuild kit handy, I'd go ahead and use it. So after cleaning it and installing the new part, I put the carb back on and tried nudging it back to life with another shot of starting fluid.
Now it isn't sparking again. What's odd is that the sator is now showing around 60Vac instead of 80. Only about .1/.2Vac is arriving at the ignition coil. I took the stator and magneto from another bike, put them on the bike I'm trying to fix and got the same results from the VM. This was with the trigger coil that was on the donor bike. So right now I'm out of ideas. The new trigger coil did produce a spark, the bike tried to start then suddenly, all on it's own, it's back to not sparking. |

A few weeks ago I did remove the wiring harness (which was very wet at the time) and let it dry out, then put lengths of marine heat-shrink tubing around every splice. The factory splices were only wrapped with a bit of electrical tape, so it seemed there was room for improvement. Also, I added and additional ground wire from the CDI's ground wire directly to the frame. My father was an electronics tech as well, he started on the in the Air Force then ended up repairing TVs and such. Thanks for your help! |
