This heavy-duty solenoid is designed to handle the high current of the Pro-Mag 44 as well as the vibrations and harsh conditions of Top Fuel racing.
The solenoid is normally closed, but when you apply 12 volts, it opens the ground path allowing the engine to run. Once the 12 volts is removed the solenoid closes to ground shutting off the magneto’s power. Solenoid can also be used in conjunction with a master cut off switch to “kill” the magneto.
One Solenoid per magneto is required.
