Im hoping someone can help me figure out my machine, 1998 foreman 450 es left me stranded in the woods when i went to start it after cutting up a tree. problem is no spark. i have bypassed the kill switch by soldering the wires together. i have replaced the coil with a new one. and also a new genuine honda ICM.. Any ideas where to look next are greatly appreciated

Have you got a neutral light? OEM Honda coil? New NGK spark plug? You can check the Ignition switch, the pulse generator, stator and other basics by following the procedures in the service manual if you have a digital multimeter.

First go through every plug on the bike and make sure each are clean and connected fully. Check the fuse and clean the grounds to the frame and motor. Many times its just dirty connections...

I hope you know..you can't put the kill switch wires together ?,,,they are not together...when you operate the switch..this grounds the spark plug, which turns the atv off. '' jerry rigging '' things is NOT THE CORRECT ANSWER !. .

Jerry rigging switches and harnesses is a bad and costly habit for sure... but connecting the proper two wires together that go to the kill switch, correctly bypasses that switch leaving the ignition switch as the only way to kill the ignition on every Honda DC-CDI system. On AC-CDI Ign. systems the opposite is true... you'd open the connection between those two wires to bypass the kill switch.

diagnosis

further trouble shooting proved to be what i should have done in the beginning. P5 alternator connector showed continuity between yellow and green wires which is bad. this lead me to the voltage rectifier continuity goes away when the rectifier is unplugged. OHMed out the component and found it was causing the problem. replaced with new and the machines runs as it should. Yes my Kill switch is still bypassed by soldering the wires together...

Ha sound like the rectifier was the issue. I had same scenario transpire. cutting tree limbs and it was idling running jumped on and it sputtered and died and my no spark saga started. I had tried new coil and cdi still no spark,checked grounds , tested kill switch nada. Just ordered one off Amazon 640 good reviews $37 hoping it also fixes my 2000 trx450es thanks for the pointers guys. NTXREDNECK on instagram god bless us all. Here is name on amazon
