[blaster12s]

started with a low battery. highsided on a berm and then quad wouldnt start. bump start the yfz and it runs great but there is no action from the start button, changed the button it self nothing new battery notihng soooooo anyideas???

[fearlessfred]

check your starter relay. i dont know were it is on your bike,im guessing under the seat cose to the batt. just follow the positive lead and u will find it. make sure its out of gear and use a screw driver across the two posts and if it starts tell use and we will go from there

[blaster12s]

alright ill try that tonight

[blaster12s]

thanks for the ideas and keep them comeingg!!

[blaster12s]

jumped the relay. it started it up.now what??? lol

[blaster12s]

changed out the ummmmm idk the name but the thing that i connected with a screwdriver and made the quad turn over. i think its the startor relay. it connects the posative and neg sides of the battery. and when i changed it out it did notihing. still no action at the start button.

[fearlessfred]

did u ck mico switch at clutch lever

[blaster12s]

yes i did. and nothing.

[srxmiller]

Did u replace the solenoide or the relay, wifes Yfz did the same thing and it was little black relay back by the batt.

[blaster12s]

i changed the thing behind the batt. more to the rear of the quad then the batt

[fearlessfred]

i would assume that u have checked the fuse .

[blaster12s]

yes i have..

[fearlessfred]

when u turn the key on do u have power to anything else

[blaster12s]

i dont have lights or neutral lights or anything i can turn the batt on to test.

[fearlessfred]

to go any futher your gonna need a test light .do u know what im talking about

[blaster12s]

yes...just found some old fenders with lights and turn the key. got a netrul light and when i push the start button the low oil light comes on.

[fearlessfred]

that agood sign . u need to check to see if u have power from the key switch to the starter button using a test light or meter if u do have power at the button, then u need to chase down the wire from the button to the starter relay that u have allready replaced . just so u know, the starter button sends power to the relay and then the relay sends power to the starter

[blaster12s]

ok thank you.

[blaster12s]

got power from the key to the start button only on 2 of the post headding tourds the key. the big loom only had power with the one blue and black wire that ran from the starter relay to the button.
HELP

[fearlessfred]

when u push the the button do u have power at the relay on the smaller wires. there is four wires at the relay ? one of the small wires might have power all the time with the key on and the other is on when u hit the button . i have never worked on your type bike but they are bacicaly the same. somebody else jump in here and help if u can

[blaster12s]

yellow/black and blue/ black have 12v when batt is on and when i hit the button the go to 0 and the other red wire stays always at 12v

[fearlessfred]

and u allready replaced the relay witha new one and batt is fully charged check your ground connections there should be a ground somewere forward of fuel tank

[blaster12s]

both grounds look good.

[blaster12s]

well i got a 2nd harness im gonna trhow on and try it lol

[slainwarrior]

check the neutral safety switch sensor that goes into the case by the shifter.. my buddy had the same problem replaced just about everything even bought a new wireing harness and it was just that 15$ part he went to a local shop to order it and the guy had a whole bunch stocked because apparently its a fairly common problem that not many people know about

[blaster12s]

ok. do you have anyidae how to cheack it??

[slainwarrior]

i think there's a ball and spring in the sensor and when its bad the ball gets stuck pushed into the sensor... the position of the ball indicates to the computer when the bike is in gear or neutral.. the spring is supposed to keep pressure on it but they wear out and get dirty

[blaster12s]

okay thank you!

[slainwarrior]

have you made any progress? im curious to see if what i mentioned was the problem

[blaster12s]

well took the entire harness off my backup bike and it started right up so next week im pulling the broken one apprt to see what broke. THANK EVERYONE FOR ALL THAT HELP!!!!!
