Sorry, my friend, the 350 Rancher does not have a bank angle sensor. A bank angle sensor is used on newer fuel injected quads, gold wings, and sport bikes. When the unit exceeds a certain angle of lean, it cuts power to igniton or fuel systems. The oil switch you are refering to will shut down the ignition system when no oil pressure is noted. Some of these oil pressure activated switches will turn off electric fuel pumps when no oil is noted. The Rancher 350 does not have this style of oil cut off switch.
Yes, the wire you speak of could be disconnected or broken or the sender may be bad. Also the cable may not be disengaging the reverse mechanism.
