TEST PROCEDURE 3 – SOLENOID ACTIVATING COIL
See General Warning, Section 10, Page 10-1.
1. Disconnect the batteries and discharge the controller.
See Disconnecting The Batteries on page 10-3.
2. Remove the two small wire terminals from the solenoid.
See following NOTE.
3. Place red (+) probe of the multimeter on the positive (+) solenoid terminal. Place the black (–) probe on
the other small solenoid terminal. A reading of 180 to 190 ohms should be obtained
. If not,
replace the solenoid.
4. If a failed diode was removed, replacement of the diode is not necessary because a diode that serves
the same function is located within the speed controller.
