Hello, i have an 88' trial boss 250 that i am having some electrical problems with. The headlight works, and when i turn the key the neutral light comes on( its in neutral ) but the electric start, and the brake light dont work, I also get NO spark. The battery is brand new, and the plug is brang new. IDK what too look for. If i had a wiring diagram it would help greatly but i am having trouble finding one. If anyone has seen this problem, or knows what is wrong with my machine please help. It would be greatly apreciated.

 

you have no spark? does the starter even turn over, click or anything? did you make sure the kill switch is working correctly?

 

No the starter will not turn over, no click, and how would i test the kill switch?


PS thank you for the quick reply

 

Might be loose wires on the solenoid. Mine did that and found a loose connection.

 

I checked the solenoid. i think... the one behind the battery mounted directly to the frame?

That's correct, mine got loose over a period of time riding due to vibration. There are also some inline fuses that might present a problem as well.

 

yea id check the line fuses if i knew where to look.

 

PS the terminals on the slolenoid are tight, and the noid looks fairly new

 

I have one i can scan for a 1999 do you whant it?

 

here's the plaris 1999 trailboss 250 sorry if it isn't aligned right my scanner was small so i had to scan 2 pictures and crop chop flip and align them to make one. this might help you idk how much diff it is from yours. if it looks all messed up click on full size and it gets perfectly clear.
