Solenoid Linkage Adjustment
The solenoid linkage connects the solenoid plunger shaft to the engine control lever.
The linkage must have minimal friction, binding and backlash in order to assure
accurate, responsive performance of the application. The setting of the linkage is
critical to both the solenoid operation and to the performance of the application.
The linkage consists of rotating joints, fastening hardware, and, where required, a
control lever. Figure 9 displays various parts of a typical linkage.
Linkage Adjustment
A misaligned linkage may not allow the plunger to bottom out. Failure to “bottom out”
will cause an internally switched solenoid to burn out and an externally switch
solenoid to “drop out”.
