LarryB's Fuel Shutdown Solenoid, SA-2775-A, 2001-12S2U1B2A, 12 Volt


100% New Premium Quality

LarryB's Synchro Start Shut-Down Cutoff Replacement Solenoid 12V

This solenoid is a new LarryB's replacement for Synchro-Start applications. It includes all the necessary hardware. It has two coils and an internal switch that disconnects the stronger coil once the solenoid is engaged. This allows a single wire setup using a mechanical double contact switch that is mounted on the rear of the solenoid to turn off the pull coil. Internally switched solenoids are best suited for applications such as standby generator sets or other applications where vibration, dirt, moisture, and excessive cycling are not present.

It carries the part number 2001-12s2U1B2A and the Woodward part number SA-4775-A.

In the installation of “internally switched” dual coil solenoids, it is critical that the solenoid plunger be allowed to travel to its fully engaged position to insure that the plunger will automatically open the internal switch and disconnect the high current pull-in coil, eliminating the chance of coil burnout. Improper linkage adjustment will cause coil burnout within 2 minutes. Please follow instructions carefully. Solenoids that burn out due to improper adjustment are not covered by warranty.
