Bail Potentiometer Test
See Figure 4-36.
1. Park the mower safely. (See “Park Mower Safely” on
page 1-5.)
2. Remove bail potentiometer. (See “Bail
Potentiometer” on page 4-70.)
Figure 4-36
3. Measure resistance between terminals (1 and 3).
Resistance must range between 3640 and 6760
ohms.
Is resistance measurement within specification?
YES Proceed to step 4.
NO Bail potentiometer is faulty; replace the bail
potentiometer.
4. Measure resistance between terminals (1 and 2)
while rotating stem (4). Low end resistance must
range between 770 and 1430 ohms. High end
resistance must range between 4060
and 7540
ohms.
Is resistance measurement within specification?
YES Proceed to step 5.
NO Bail potentiometer is faulty; replace the bail
potentiometer.
5. Measure resistance between terminals (2 and 3)
while rotating stem (4). Low end resistance must
range between 1190 and 2210 ohms. High end
resistance must range between 4410 and 8190
ohms.
Is resistance measurement within specification?
YES Bail potentiometer is good.
NO Bail potentiometer is faulty; replace the bail
potentiometer.
