i am fixing a 400 for a friend of a friend type deal.
i was told that it has been sitting 4 years, needs a battery and carb cleaned. it was at some point at a dealer and some switch was replaced but unknown as to what was really done.
it has several issues i am attending to.
things i have already handled
replaced battery
made new positive battery cable
soldered new end on negative cable and heat shrunk
soldered broken throttle warmer wires together
cleaned and remounted starter solenoid.
pulled carb and gave it a cleaning, need to get new oil line before remounting.
sprayed cylinder with wd 40 to hopefully prevent or lossen up any stuck piston rings.
things that still need attention:
hand warmers
fog lights, rear light
exhaust leak at engine mounting point.
that is all i can see at this time but could be more as things go along.
i am a bit new to the atv world but i am a professional mechanic so not afraid to dig into things.
what i am having issues with are the hand warmers and throttle warmer. i have traced the wires down to the "board" for lack of better term. i see that it has a switch(mounted onto plastic fairing) that has three positions, and assume that is is supposed to be off,low and high heat?
now the wires are running from the switch to the board to a resistor and back to the board if i am looking at it correctly. i would think that it should be one of the wires coming off the resistor should go to the warmers/ one side of switch? BOTH hand warmers need to be replaced at some point i just want to understand how it is supposed to work.
what i see is 1 of the black wires that should supply the circuit is unhooked but where all the black wires go to on the board there is no power. i have a red with black stripe wire that has power but is is hooked into the engine off sw that grounds the coil. that meaning it is also key on power.
now i could just hook all that up and see what happens but i am unsure where some of those black wires are going. if needed i can provide pictures.
I also do not know how to find the year for this machine so if you could help me with that. then could you point me to a wiring diagram?
thank you for your time in advance.
