Finally got a spark, but it's acting weird, sometimes I get shocked and the spark is weak and sometimes it jumps from the threads to the electrode. Does anyone know the gap measurement for the pulse generator / crank position sensor? Thanks

Ugh no luck, found the resistor it reads 99.2 ohms, also tested from the resistor end to the black/white end at the connector on the wireloom also 99 ohms. At this point, I'm going to put it all back together and try another CDI, I don't know what else it could be at this point. Can I mail anyone my old CDI's to check on there bike?

Yes the bike ran about a year ago with the original ignition switch, I was dialing in the carbs when it just wouldn't start again, found it had no spark and Ive been looking for the problem ever since. I do remember the spark being very weak before working on the carbs. Ive checked and rechecked this as well as the continuity of all the associated Black/white neutral lines it connects to. Im using a car battery while testing, plenty of cranking power I'm going to take apart the ignition switch and look for and test the resistor today.

Im in Paso Robles CA. Yes it turns over. I do not have an aftermarket barrel, I just by passed the ignition barrel still no spark, or I have it wired as factory with a factory ignition barrel still no spark. I'll test for resistance, do you know what wire to test for resistance into the CDI? Thanks for all the help

I haven't bypassed the ignition barrel yet, I've only checked to make sure I have continuity on the 3 circuits. I went back and checked the signal generator for voltage, I get the correct ohms on both on them but with both signal generators I only get 1v or 2v when checking the blue and yellow wire?

Well still no spark, tested both CDI's again, I don't know if both are working correctly one is from Eblag and the other is the original that came with the bike that ran 6 years ago. I just double checked the continuity on everything that I could think of, from the coils to the ignition key switch, no issues there. Also unwrapped half the harness didn't see any issues. Any chance on a short in the alternator? Maybe both CDI's are bad?? Not sure how to check if they are working correctly. Also on the wiring diagram there is a 4 prong connector for the neutral switch a blue, Red/Black, Green/Blue, Black/white I cant seem to locate that connector and the Red/Black, Green/Blue from the CDI just ends??? I'm out of ideas, other than replacing harness and getting another CDI

Thanks for helping out with this problem, it's been driving me nuts for the past year, I feel like I've checked everything, and I finally broke down and had to ask for help. Yes I'm getting 12v at both the coils, also just checked the 3 circuits on the ignition key switch, all good there, and still no spark at either coil. "Are you getting a pulse from the ATU on the crank? " is that checking for voltage from the crank position sensor?

I have a 97 Bandit 1200 that is having a no spark problem that is driving me insane -No spark from both coils -both coils read around 3 Ohms - I’ve used 2 signal generators both are 170 Ohm and 166 Ohms - I’ve by passed the safety side stand switch and clutch switch - Checked all wiring, and grounds - I’ve tried 2 different CDI units, still nothing. - New spark plugs - New battery - All fuses are good - New starter solenoid Out of ideas, and help would be greatly appreciated
