97 fourtrax 300 no power or ignition

Alright so I just bought this quad. When I bought it I had to replace the ignition switch, so I did. I had yet to buy a battery so I tried to kick start it. The neutral light would light up but I had no spark. I put a battery in it and the solenoid was bad so I just jumped the solenoid and the quad would turn over but still no spark. I ordered a new coil and solenoid, replaced the parts and now I have nothing. No neutral light, nothing happens when I jump the solenoid. I had a spare kill switch panel and installed it as well, this didn't make a difference. Sorry for the lengthiness but I'm tryin to relay all the Info. Thanks for any help.

The only Chinese crap I got was the solenoid. 6 bucks can't beat it. Ok so now I have power back to everything. I found a bunch of free floating wires that had exposed sections. I also found out whoever owned it before had switched the alarm box wires and icm wires. So I wired according to the manual. I still have no spark. What's my first move now?
Also I verified the kill switch is good. I have power flowing thru the black and white wire out of the switch.
Will the reverse switch kill spark? The light doesn't work.
The solenoid works though, and I guess the way I phrased my last post was misleading. They didn't cut any wires. The alarm box and cdi both have 4 wire plug and a 2 wire plug. They just had them plugged in wrong, so the wiring harness isn't damaged other than the few grounds that had exposed areas. I spliced those back together using hear shrink butt connectors
until you get the neutral/reverse switch fixed ?, it won't fire the spark plug.
so a faulty reverse switch will kill spark?

The alarm has a 3 wire plug and a 2 wire plug = 5 wires total. The CDI has a 4 wire plug and a 2 wire plug = 6 wires total. They can't be mistakenly swapped... so something is wrong here. Did someone switch the wires in the plugs between the alarm and CDI? If so, that indicates either the wrong part(s), china made part(s), or the harness was swapped or hacked on.

You'll still have to replace that china solenoid... and the wiring harness is still a major suspect. I'd replace them both before going any further.

You said your neutral light works so you are good to go there.

Also, if your CDI was wired up wrong...? You can't expect it to work once everything has been corrected.
alright so the plugs are interchangeable between the cdi and alarm. They are the same plug but yes one plug has 3 wires and the other has 4 wires. I got all three alarm lights workin now too, still no spark. The wires into the Cdi are (blue/yellow, green,black/yellow, yellow white) In one plug then (black/white, light green) in the other connector. Is that right?
