A couple years ago my rhino started acting funny when starting, you couldnt hold the key in start position to start it, you had to just bump the switch and it would fire up....recently it totally quit firing while holding the key down in start position but if you just bump the switch it will spark here and there....The weird thing is that i can unplug the rectifier and it will fire like a champ and never miss a beat.... ive installed a new key switch, new rectifier, and new coil and still the same thing....has anyone ran into this problem before?? any help is appreciated...
