Troubleshooting a no spark issue, was running OK, maybe a little rich, turned it off, now no spark. I've checked/ohmed out the main key switch, the start/stop switch, neutral switch, brake switch - all good. It will crank the starter, but no spark with the starter or when I try the pull start. I've checked all fuses and diodes. Swapped battery. New plug. New coil. Swapped in a used CDI - no help. Traced, removed, cleaned, reattached all grounds. Removed things like my winch from the circuits to be sure a bad relay or something was dragging it down. When testing voltages, the orange wire going from the CDI to the ignition coil shows no/very low voltage-shouldn't it have 12V on it? Sometimes I get a very weak, intermittent glow on my spark tester, but not enough to fire the plug. I've checked continuity on just about all wires in the harness. Checked/cleaned/lubed w dielectric grease- all connections, redid a few that looked old/dirty. I've checked the stator resistances, all good, but have a stator and rectifier ordered anyway, will arrive Sunday. I verified that the rectifier has a voltage output back to charge the battery while cranking - 10.5-11V, low, but expected while starter is engaged. What else can I check as part of troubleshooting? I have a Haines service manual, but the 1999 350 4x4 seems to be an odd model, there isn't an exact electrical diagram for it, but found one for another year that has all the same number of wires and same color wires, so I've referenced that. Any hints, tips or advice would be appreciated! Thanks!

i just picked this up. was told ran fine but overheating issues led to replacing head gasket and head. has not ran since. he is not a mechanic but helped someone else who he could not get back to finish job, got aggravated and put up for sale. i was thinking timing issues. i have 110-120psi on all 3 cylinders so i think valves are correct. dont know about distributor yet. however i have no spark. i have no power going to ignition coil. tried to follow white wire but gets lost in wire harness. does anyone have a wiring diagram? can anyone tell me what conditions have to be met before starting. motor turns over so i would think all safeties are met but you never know.

Question for you guys. I have a 98 bayou 220 that I picked up cheap cause it's wasn't running. So it's has very low compression. It is getting spark and fuel.
What should my next course of action be? Any other tests I should perform or where to start looking?
Thanks in advance.

Need some feedback here. I picked this machine up with PO saying no spark. I have tried new stator, CDI, and coil. The stator ohms 231 w/r to w/g and .1 red to blue. The coil is .8 primary and 2.53 secondary. I have 12 to the CDI with ign on and the wires from stator to CDI have good continuity. This model only has 12v on or off for ign/kill source. Still no spark?
