Good To Know
Q: How does the glow plug function work? A: Turning the key to the designated glow plug position energizes the intake heater or glow plugs for a set time. This pre-heats the combustion chamber to aid in cold starting.
Q: What is the function of the 4 positions? A: The switch typically includes Off, Accessory, Run, and a combined Glow Plug/Start position, allowing for sequential control of power and pre-heat. This consolidates multiple switches into one unit.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
