1. Turn the key switch to OFF and place the forward and reverse switch in NEUTRAL. Leave the batteries
connected and leave the Z plug connected to the controller.
2. Place the black (-) probe of a multimeter, set to Volts DC, on the negative (-) post of battery No. 6 and
place the red (+) probe on the large post of the main solenoid (with 6 gauge yellow wire attached) (Fig-
ure 21-25). With the key switch OFF, the reading should be Capacitor Charge Voltage (approximately .8
volt below Full Battery Voltage). Turn the key switch to ON; the reading should be Full Battery Voltage.
3. If there is a no voltage reading, check batteries and battery wires. Check voltage to the Z1 position in
the Z plug. If all these components are good and still there is no voltage reading, replace the controller.

Test Procedure 7 - Voltage to Main Solenoid Coil
1. Turn the key switch to OFF and place the forward and reverse switch in NEUTRAL. Leave the batteries
connected and leave the Z plug connected to the controller.
2. Place the black (-) probe of a multimeter, set to Volts DC, to one of the small posts on the main solenoid
and place the red (+) probe on the other small post on the main solenoid (Figure 21-26). With the key
switch OFF, voltage reading should be zero. Turn the key switch to ON, the reading should be full bat-
tery voltage. If the reading is full battery voltage and the solenoid does not click, replace the solenoid.
