MAIN SOLENOID CONTROL CIRCUIT (FIGURE 21-7, PAGE 21-8)
The Main Solenoid Control Circuit supplies voltage to the solenoid activating coil. When the key switch is
turned to the ON position and the two second (20 seconds on some early models) time delay transistor in the
speed controller is on, the circuit is complete and the main solenoid coil is activated, closing the solenoid
power contacts.
The Main Solenoid Control Circuit consists of:
• The Solenoid Activating Coil.
• The Key Switch.
• The 18 Gauge Green Wire From the Large Post of the Solenoid to the Key Switch.
• The 18 Gauge Blue Wire From the Key Switch to the Small Post of the Solenoid.
• The 2 Second Time-delay (20 seconds on some early models) Solenoid Shut-off Transistor Located at
the Z4 Position on the controller.
• The 18 Gauge Blue/White Wire From the Z4 Z Plug Position to the Small Post on the Solenoid.
When the key switch is turned to the ON position, the solenoid is activated and there should be an audible
click. If the accelerator pedal is not depressed within 2 seconds (20 seconds on some early models) to acti-
vate the controller, the controller will shut off the main solenoid. The controller disables the solenoid by turn-
ing off the transistor at the Z4 position.
While the vehicle is in operation, the controller will turn off the Z4 transistor and deactivate the solenoid if the
accelerator pedal is released and is not depressed again within 2 seconds (20 seconds on some early mod-
els). If the solenoid is shut off by the controller, it will activate when the accelerator is depressed.
