hi im new to this great forum and im old on frustration
i have a 2002 sportsman 500 ho that is currently making me go CRAZY !
i have no spark

i replaced the distributor cap (spark plug boot) still no spark!
stator was replaced NO SPARK!

tried new coil not the pickup coil just the regular coil ! no spark!

ohmed out the pickup coil 96ohms. book calls for 500 ohms. is this my problem ??? if so i found a new pickup coil on ebay for $40 brand new but the seller states that it ohms out @ 125ohms will this work in my machine seeing how the book calls for 500???

also could i have a bad cdi box & how do i test it
i need some help im running out of hair thanks

Ignition coils produce spark through a simple process called mutual induction. Run 12v DC into a coil of wire surrounding another coil of wire, break the current and the rapid collapse of the magnetic field induces a much greater voltage but lower amperage into the inner coil. Enough voltage to jump the spark plug gap seeking ground. If you have 12v dc and a signal (Sudden ground) it should produce a spark. With no moving parts an ignition coil rarely fails.

At some point you really need to take your vehicle to a dealership.

Before getting too involved, did you positively eliminate the kill switch on the handlebars? I've seen people tear their machines apart only to find the switch was off or defective.

i have disconnected the black wire from the cdi box going tward the head still no change
is their any way to bench test my cdi box or do i lean tward my pickup coil ???

I want to say ,that your pickup is ok, book says 97 ohms--white to white/red wire
white to ground --- infinity

Are you sure you don't have a bummed coil wire--should read 10400 ohms w/the plug cap on- wiggle it around and watch the meter for any change

I had the same problem and found mine last night, I had the pickup coil too far away from the flywheel so the coil wasn't picking up the magnet when it passed by. I gapped mine with a dollar bill, yes the thickness of the dollar bill should be the gap space. The coil needs to be as close to the flywheel as it can without hitting it. Check this, may be your problem as well.

checked my pickup coil gap its good
checked my coil wire tested good
still no spark!

using a meter what schould be my reading out of the cdi box going to the ignition coil i have no reading at all!
and the brown wires that are on the coil are all ground correct???

what do i do im loosing patience!
