Test Procedure 5 - Solenoid Activating Coil:
1. Remove Diode terminal end from the small post on solenoid (with 18 gauge yellow wire attached).
2. Make sure that the diode direction is correct (Figure 20-2, Page 20-3, or Figure 20-3, Page 20-4). The
red terminal end of Diode attaches to small post on solenoid (with 18 gauge red wire and 18 gauge
white/black striped wire attached).
3. Using a VOM or continuity tester, check for continuity between both diode terminals. Reverse the tester
leads and again check for continuity. A diode is designed to conduct current in one direction only. If a
diode shows continuity in both directions or does not show continuity in either direction, replace the
diode assembly.
4. Remove the diode assembly and the yellow wire from the small activating coil post of the solenoid and
place the red (+) probe of the VOM on the post. Place the black (-) probe on the other small activating
coil post on the solenoid. A reading of 190 to 250 ohms should be obtained. If not, replace the solenoid.
If the ohm reading is correct, reconnect the diode assembly and yellow wire.
POWER CIRCUIT
Test Procedure 6 - Forward/Reverse Switch:
1. With the Forward/Reverse selector in the forward position, place the red (+) probe of VOM or continuity
tester on the M- terminal lug of the speed controller and place the black (-) probe on the S1 motor ter-
minal. Meter should read continuity.
2. With the Forward/Reverse selector in the forward position, place the red (+) probe on the A2 motor ter-
minal, and place the black (-) probe on the S2 motor terminal. Meter should read continuity.
3. With Forward/Reverse selector in the reverse position, place the red (+) probe on the speed controller
M- terminal and place the black (-) probe on the S2 motor terminal. Meter should read continuity.
4. With the Forward/Reverse selector in the reverse position, place the red (+) probe on the A2 motor ter-
minal and place the black (-) probe on the S1 motor terminal. Meter should read continuity.
If continuity reading cannot be obtained, and all wires and connections are correct, see Forward/Reverse
Switch, Page 20-27.
Test Procedure 7 - Solenoid Contacts (Power Off):
As stated in WARNING above, follow procedures exactly.
1. Remove the yellow wire and red wire from the large posts of the solenoid. Remove resistor assembly.
Place the red (+) probe of the VOM on one of the large posts of the solenoid and the black (-) probe of
the meter on the other large post on the solenoid. It should show no continuity. If the VOM shows conti-
nuity, replace the solenoid.
2. Using a VOM, check for continuity between both resistor terminals. If reading is not approximately 250
ohms, replace the resistor.
• WHEN MAKING ELECTRICAL TESTS OR REPAIRS, ALWAYS:
- WEAR SAFETY GLASSES OR APPROVED EYE PROTECTION.
- REMOVE THE KEY.
- PUT THE FORWARD AND REVERSE SWITCH IN NEUTRAL.
- DISCONNECT THE BATTERIES AS SHOWN (FIGURE 20-1, PAGE 20-2).
• FOLLOW ALL PROCEDURES EXACTLY AS INSTRUCTED.
• SEE THE SAFETY WARNINGS ON PAGE 20-1.
