Ok i got one for ya. Bought quad 5 months ago. Needed battery.....just clicked when button pushed. Pull started fine , headlights worked.... all good. Had to replace rope for pull start and it seemed to want to stick sometimes and man it takes up 20 min sometimes for a cold start but runs and idles great once it fires.....crazy. Anyways tired of pullin amd wife n kids wanna ride when I'm not home but they cant pull start it for 1st start of the day. Ok now the problem. New battery, new relay, checked solenoid, and traced all wires -good. Then turmed key on wont click and now headlight didnt work.......note it didn't click after having it for a couple months when i tried to push button. Whats weird is i checked the bulb, wires andd swith and they are good but the tail light was still as always on when i turmed key and switch to on.
By that time i was fed up for the day. Heres the weird part ....went out next day and cleaned all connections that were dirty lookin and gave it a try......turmed on key and switch now no tail light. Does anyone know what else to check? I have a feeling if i figure this out i will end up not getting lucky and have to replace the starter but i need help figuring this out first before my next let down lol
