So guys, I've got some bad news.
I ordered a total refresh kit from dratv for the "ac generator and points/condenser." It comes with new magneto and generator windings as well as the typical points and condenser. Plus a bunch of small parts. Good buy for 50 bucks. I replaced everything today, along with replacing the coil with one I got off amazon.
No spark.
(please refer back to the wiring diagram on page one to familiarize yourself with the circuit)
The timing for the contacts is perfect, the gap is perfectly spec and the condenser is connected correctly. I did have to reuse the old points, because the new ones werent in spec and during adjustment half of the two part contact broke off. I used a flat file on the old ones, they look shiny. The new coil comes with the boot on it, so it's not a matter of having a resistor cap or anything.
Before replacing parts I had 6 volts ac on the magneto to coil wire, now I'm getting between 11 and 19 on a good kick. The new coil did have two low voltage wires going to it, where the original had a case ground. I put the green wire to ground, black/stripe wire to input. That seems correct after I ohmed each way through the new and old coils to compare.
Just like before, I'm getting roughly 1000 volts on the high side. Not enough. What's the problem? What's happening here? It's seriously killing me. I suspected that possibly the ignition switch could be faulty inside, so I pulled that and desoldered the coil signal wire to ensure it wasn't constantly grounding it. I checked the switch for correct operation on that circuit once I had it disconnected, then ran an ohm test through the coil signal wire to ground to see if it was shorted. Accounting for the resistance in my leads it was around .6 or .7 ohms to ground. That sounds very low, but in actuality the magneto winding was under an ohm and the coil wire (in parallel) is around an ohm and a half I think. Using those numbers the expected result would be .42 ohms, making it hard to actually test a short to ground. It's so close to zero.
Do you guys have any other suggestions? My stepdad just said take the flywheel off and wipe clean the magnet surface, and I agree I could clean it better than I did but I don't think that's the problem.
I'm open to any suggestions, guys. Seriously. I've never had to work on any one vehicle this long in my life. It's driving me insane. And I'm not even getting paid for this one!
Thanks again for any help
