not online computer friendly-it took me an hour to figure out how to post this. I'm new to this forum stuff. I bought a 2001 450S last month that has no fire to the plug. the last owner said he shut it down one day & it wouldn't start-no fire. I have a honda manual & checked it out . the pulse generator is only making .2-.3 volts while cranking. I installed a new one that had the same ohm resistance as the old one & checked the wire & -ground-same low voltage.Is there a cranking rpm listed anywhere? I have battery voltage to the ICM while cranking. Anyone have any thoughts? Any help will be appreciated.

welcome to the forum !!
have you checked the on - off switch on the left handlebar ......the contacts can get gummed up and even if it says run its on off .(just move it to run and stop a bunch of times, it may clean up the contacts )

Foreman 450 no fire

After reading many posted forums,i decided to check my battery charge voltage regulator. Manuals don't tell how to check ,but they have diodes inside-you should get continuity only one direction between the tabs where the three yellow wires connect and tab where green ground wire connects. If you get no continuity or have continuity both directions,then your regulator is bad.the manuals don't refer to this test as for troubleshooting a no fire to spark plug.beleive me, i've spent many hours checking everything the manuals refered to and this was the only thing causing the engine not to fire.i hope this info. Can be used by others experiencing this problem-it seems i've read alot posts that no one ever listed what was causing their ignition problem assuming that they did eventually solve the problem. A new regulator made me very happy to see a blue arc on my spark plug. Thank you all for your posts

My cousin had the same no fire on his rancher and replaced the stator, same thing. He replaced the voltage regulator/rectifier, problem solved.
