Got an email and this chat showed up. Good to see Doorfx here! He said what I was going to.....sounds like a the key switch...but.....with electrical it can always be something funky. Of course U want to be sure U have good ground...good bat hook up and all the basic bla bla bla in that dept. Yes, a test "light" is nice but it has only certain skills...I luv my cheap little red HF multi I got for free ...it's bailed me out many times. You said U found a wire rubbed raw...did that wire short out? blow a fuse...or damage the computer...is there an "in line" fuse unknown yet? What about a simple safety sensor issue. like the handlebar kill switch....and others....Arctic cat had issues with their Temp sensors I read....could that be enough not to pass the needed "every things ok" current to start the machine? crank sensor....safety/neutral switch/sensor...and so on. and nobody likes to say "the brain box" as that's normally and expensive thing...Go back to basic's...BEFORE U go that route...double check simple things....kill switch...ign....sensors...fuses...pull them out put them back in....relays..pull them out put them back in...or if U have TWO IDENTICAL ones...switch them...remember I said IDENTICAL...and so on...simple checks first... the go to the brain box and check in going and out going...cuz that controls the cluster and the pump to my understanding. no? yes?
