I've got no spark on my 1996 DR650. All resistance coil checks are within specs: Ignition coil: .2, ohm primary, 24K secondary. Stator charge coil: .13 ohm. Pickup/trigger coil: 205 ohm. No shorts to ground. I have +12vdc on O/W wire to CDI with key on and B/W pin on connector has continuity to chassis ground and battery negative terminal. So I replaced the CDI box - Still no spark. So I replaced the stator with trigger coil - all resistance measurements within specs - still no spark. Can't start it, so I measured AC peak voltage output of the pickup coil (blue and green wires) while cranking at 4.5vac. Measuring with the 4-pin connector unplugged from the CDI. Waveform on an oscilloscope looks good. The source coil output (black and white wires) is only 0.6vac peak. I was expecting 70-90vac cranking and a few hundred when running. Swapped back in the original stator and got the same 0.6vac out of the charge coil when cranking. I've got no ac power into the CDI on the black and white wires. I'm suspecting the flywheel magnets are damaged, but the magnetic pull is strong, with uniform spacing between the strongest attraction force when I run a piece of steel around the flywheel inside diameter. For reference, all 3 legs of the 3-phase generator coils are putting out 17vac when cranking, so the magnets seem ok. Can anyone tell me what the correct ac voltage out of the ignition charge coil (black & white) should be? I can't believe half a volt can charge the CDI enough for it to put out a couple hundred volt pulse to the ignition coil. This one has me stumped - suggestions appreciated.
