I made the others, Ya'll make this one. find it, link it, post it, whatever.
Check the voltage on the switch. If its like 4.7, then check the speed sencer. If there is no voltage on the switch, then you should have a flashing 2/4wd light. If not, check the connections to the relays. They are at the back by the roll-over sencer.My bike's 2/4wd doesnt flash, it just doesnt engage at all.
no motor noise, except for the belt housing kebc making a racket when the key is turned off.
Flipping the 4wd switch does nothing bike just says 2wd.
