Polaris Scrambler 400 no spark
I have a 96 scramber 400 2 stroke . The problem started when i lost the keys, i tried to jump the switch and i assumed i fried something. i have replace the coil, cdi, ignition switch, and stator. i also took the wiring harness all apart and didn't find anything burnt/melted/shorted. I have run out of ideas. oh ya i also noticed that even with a fully charged battery, the started soloniod only clicks, i dont think that would have anything to do with the spark problem. Help!

Regulator voltage shouldnt cause the spark problem. These old models are magnetically triggered ignition systems. The stator harness branches off to the ignition system and to the charging system. The battery is just for the lights,starter and awd system and the regulator to keep the battery up. You can pull start these with a completely dead battery. Keep checking for bad grounds or shorts or a shorted out thermal fuse (in the black plastic pouches)

Hi thanks, i found a bad ground at the coil, (were it is attached), still no spark, then i removed the black wire at the reverse limiter, and got spark........thanks so much ur a huge help!!! I do have one more question, the stator i put on has a slight adjustment on it, are there any markings on it to adjust the timing.....it seems to be a little off

Similar Issue.
Here is the story...
The scrambler was running fine but the starter didn't work. I purchased a new one and went to put it in. During the install I couldn't get the fly wheel off so I used a screwdriver to hold it which busted the stator. I purchased a new stator and bolted everything together and its not working. I have a book for diagnostics but it lists a series of models but not exclusively mine...
Here is what I have, a 97 400 4X4 scrambler.
The stator after replacing it has these readings.
brown/white to White = 1.2 ohms.
Brown/white to Red/Black = 114 ohms
White to Red/Black = .6 ohms.
Is this new stator bad and / or does anyone have any suggestions.

I just wanted to say to the "Old Polaris Tech" that you are an invaluable resource in this forum. I mean, you have helped me more than you will ever know and I am very grateful for your vast knowledge of the Polaris ATVs. Thanks again, and I hope you never stop posting.
