I have 99 foreman 400 and it has lost all spark. I have replaced coil, cdi box and trigger coil and still no spark. I have also checked most of the wires with an ohm meter nothing is showing bad so far. Any ideas would be appreciated. Also if anyone has the wiring schematic for this machine it would great if you could send it to me. I think I traced most of the wires execept 1 or 2. I am about to pull my hair out.

 

My email is apwirth@yahoo.com

 

Do you get a neutral light? It wont spark with out it.

 

yes the neutral light comes on

 

Have you tried bypassing the kill switch and ignition switch? The kill switch is in the run position?
Tried a brand new spark plug?

 

I have not tried bypassing ign or kill switch yet that was my next move once i get a schematic. As far as the spark plug I have not changed it but I have a coil tester and it is not doing anything.

 

I have finally got this thing started but i still need a wiring diagram to find out why i had to jump a circuit. There is a yellow wire coming out of the cdi box that needs a power source to ignite the coil. I do not know where the yellow wire gets its power. I noticed when running tests that it did not have alot of volts so I ran a new temporary wire from battery down to cdi box and it started right up. I could just leave it that way but I want to fix the problem properly.

SO IF ANY ONE HAS A WIRING SCHEMATIC FOR A 99 FOREMAN 400 IT WOULD BE HIGHLY APPRECIATED. EMAIL IS apwirth@yahoo.com.

Also if anyone knows exactly where the yellow wire goes to (im assuming stator or voltage regulator) please enlighten me thanx.

 

I work tomorrow so I will check the shop manual there We just do not see many of those in for service so I am not exactly familiar with the wiring and specs.
Hopefully I will not forget

The yellow wire comes from the stator, check that plug(by the left engine case), and make sure its clean inside, and the pins and sockets contact each other.

 

Hondabuster is right. Yellow wire on the outside end of the voltage regulator runs to the stator. Half way between there it T's off and runs over to tie ICM
