Good To Know
Q: How does this neutral switch function in the starting circuit? A: It interrupts the starter motor circuit unless the shift lever is in neutral, preventing accidental starting in forward or reverse. This switch is used with your ignition key to complete the circuit only in safe gear position.
Q: What should I do if the engine still cranks in gear after installing this switch? A: Verify the shift cable linkage is properly adjusted and that the shift mechanism engages the switch lever fully. A misaligned shift linkage can bypass the neutral signal even with a functional switch.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
