Good To Know
Q: Is this relay suitable for both Western and Fisher plow lifts? A: Yes, it is commonly used in both brands' systems, but verify the mounting bracket and terminal spacing, as these vary slightly between model years.
Q: What happens if I use a lower-amperage relay? A: A relay rated below 150A may overheat and fail prematurely, so this unit is recommended to safely handle the motor's initial surge current.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
