87 Warrior Stator Interchange & Diagnostics

[dcg4403]

Greetings,

I've ordered a cylmer manual for my 1987 Warrior but won't have it until next week. Hoping someone with a manual or knowledge can help me out.

I've got no spark so before blindly ordering parts I'm trying to diagnose the exact problem. I'm assuming it is the stator as it appears to be the high failure part but could be coils or rectifier or even wiring.

Because I have the original model, I have a Type "A" stator connector. Which is a 4-wire plug, 3-wire plug and two individual wires. See image. I'm not sure which leads need to be ohm tested and the ohm ratings?

Also, can someone tell me which stators interchange across models and years? I've read that Big Bear & Banshee parts interchange but would like to confirm.

Thanks a bunch, Devin

On the 3 white wires coming out of the stator, they should all have 0.7~0.8 ohms resistance in all three combinations. That means imagine numbering each white wire either 1, 2, or 3. Check 1 to 2, 1 to 3 and 2 to 3. Also, check any one of the white wires to the laminated iron core of the stator. ANY continuity to ground indicates the stator has had an insulation breakdown and will have to be replaced.

To test the Source coil (for the ignition) connect your pocket tester from the white/green wire to the red wire. Resistance should be 270~330 ohms resistance.

To test the pickup coils, connect your tester from the blue to the yellow wire. than green to white Resistance should be 171~209 ohms resistance.

BONES, you rock my friend!! Glad to see a knowledgeable early year owner. Hopefully, I can give back to the forum in the near future.

Trying to restore this Warrior to former glory! Of course without spending much money!
