Bought a 88 big bear 350 4x4 took it for a run and lost spark, found it was stator so I replaced that then took it for a long run and it sat for 2 days and no spark again, this time stator tests good on ohms and voltage for source and pick up coils so I started replacing things including regulator, ignition, ignition coil and plug cap, spark plug and everything tests great including all safety switches until the orange wire for ignition coil from the cdi it only reads 3 volts so I replaced the cdi and still 3 volts, any ideas??

Fixing for a friend. Atv was at a different friends house to be fixed and he rebuilt the carb and had it running nice, then it shut off and no more. He replaced the key and the coil.
So he got busy, so I am helping, I checked the wiring from the stator to the cdi, and from the cdi to the coil. All is good. I checked resistance on the pickup coil, good, and on the source coil, open. I buy a new stator (China) and the 4 prong plug only has 3 wires in it while mine has all 4. I checked resistance in the source coil and it's in the 300's. I pulled one of the old pickup wires out of the old stator and wire it in the new one. Still no spark.
Why do the wires differ, I checked the VIN again and it's "J" for the year and I got a 1988 stator. Please help!

Hello all, I have a 2006 Polaris Sawtooth with no spark. It has a dead battery but with a jump pack on it, it will still not Spark. Plug is good, Throttle ETC is not closed, Stator pick up coil seems to Ohm out in the correct range, Unsure how to properly check the CDI. And when ignition is on the Neutral and reverse light come on but after cranking just the neutral stays on.
Any help would be great,
Thanks!

My 1992 TRX00 recently stopped firing. I understand this is a common problem. I have ordered an aftermarket CDI unit. TJ

Background,
This winter (Dec.) I was plowing and everything just died, just quit. No lights, no pull start, No nothing. I've had this problem before and I changed the voltage reg and it ran fine for over a year. Then this. So I changed it again, thinking this was the same problem. Tried to start it and a small pin hole in the CDI appeared with electrical smoke.
Months go by and I finally decide to just replace parts (I'm Horrible at electrical issues). I changed the stator, new CDI, new Voltage reg, new starter solenoid, tested the starter (prefect), charged the battery.
Went to start it and the solenoid rapidly clicked. All the dash lights on, headlights work. Pull stared it and it fired right up no issues. Looked into the rapidly clicking starter solenoid and it was not enough juice in the battery. Took the battery completely out and hooked up a jump box to it turned the key, light on, everything looks good. Pushed the starter button and it fired right up ran great. Turned it off to test it again, Turned the key and nothing. No dash lights nothing. Took the jump box off and pulled started it. Started it right up. Re-hooked the jump box, still nothing.
Any Ideas?
