Here is a diagram of the Meyer Toggle Switch Wiring.
(Looking at the back of the switches)
|To:||Must Have Power|
|Raise||Red and White Wires|
|Right||Green and White Wires|
A Coil – On pump, Black Wire – Controls Lower
B Coil – On pump, Red Wire – Controls Raise
C Coil – On pump, Green Wire – Controls Right
Motor Solenoid – Under Hood, White Wire – Turns on plow Motor
Left angle is default. If the motor runs and no valves open, the plow goes left.
On older Toggle control harnesses the power wire was black with an inline 20 amp glass fuse.
On newer Toggle control harnesses the power wire is dark blue with an inline 20 amp ATC fuse.
There is no ground wire for toggle switch controls.
Older Meyer Motor Solenoids had a single small terminal, where the white wire is connected. The Mounting Bracket on the Motor Solenoid had to be mounted to a good ground for the Motor Solenoid to work properly. The current Meyer Motor Solenoid has two small terminals, the White wire goes to the ( S ) Terminal, and the ( I ) Terminal must be grounded for the Motor Solenoid to work properly.
And finally, for all those who call us wanting to use “normal” on/off toggles to work the pump, NO. It is not that simple.
The Raise/Lower switch is (ON) OFF ON. The (ON) means it is a momentary switch in that position. When you press it up, it will run the motor until you let go, then it spring returns to the center OFF Position. When you push it down, it will lock ON in the down position to allow the plow to “Float” and follow the contour of the pavement.
The Angle switch is (ON) OFF (ON) indicating that each of the (ON) positions are momentary. When you press the switch in either direction, it will run the motor until you let go, then it will spring return to the center OFF position.
Additionally, BOTH switches have the center power terminal bonded, feeding both poles of the switch.
