4. Using a multimeter set on ohms (
Ω
), measure the secondary coil resistance. Place the red (+) probe of
the meter on the plug lead (3) and place the black (-) probe on the primary wire terminal connector (2)
(Figure 12-31).
5. If the resistance is not within 6.0 - 11.0 k ohms (
Ω
), replace the coil.
6. The first five steps will find 90% of the bad coils. Some coils may bench test okay but fail under a load
due to heat while operating. Another method of testing is to replace the coil and then run the engine. If
the engine runs properly, keep the new coil in the circuit.
Test Procedure 14 - Disconnected Kill Wire:
1. Place the neutral lock-out cam in the SERVICE position, put the forward and reverse lever in the NEU-
TRAL position, and chock the wheels.
2. Remove the spark plug wire from the spark plug. Using an ignition spark-gap test tool (Thexton 404®
or equivalent), check for correct spark to plug. Adjust the tester probes to approximately to 18,000 volts
(18 Kv) setting. Connect the tester to the spark plug wire, and connect the alligator clip to the top of the
spark plug (Figure 12-28, Page 101).
• 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 BATTERY AS SHOWN (FIGURE 12-1, PAGE 82).
• FOLLOW ALL PROCEDURES EXACTLY AS INSTRUCTED.
• SEE THE SAFETY WARNINGS ON PAGE 81.

• BECAUSE THE IGNITER IS LOCATED WITHIN THE COIL HOUSING AND IS IN PARALLEL WITH
THE COIL, IT CANNOT BE TESTED SEPARATELY. HOWEVER, IF THE RPM LIMITER (TEST
PROCEDURE 12) IS GOOD AND THERE IS NO CURRENT TO THE SPARK PLUG LEAD, IT CAN
BE ASSUMED THAT EITHER THE COIL OR THE IGNITER IS BAD. IN EITHER CASE, THE COIL
ASSEMBLY MUST BE REPLACED.
