Alternator Test

5. Perform the Positive Output to Field test on the alternator:
• Unplug the battery from the power control board
• Remove the black wire from the B+ terminal on the alternator
• Remove the brown wire from the field terminal on the alternator
• Place a short wire with alligator clips on the B+ terminal and the
field (FLD) terminal of the alternator
• Step on the machine for approximately 10 to 15 seconds
• If full resistance is achieved during this time, your alternator
has correct current flow. If no resistance is achieved, replace
the alternator.

Resistor Test

6. Unplug the load resistor from the power control board and set your
voltmeter to Ohms. Place one lead from the voltmeter on each of the
threaded posts on the load resistor. Replace the load resistor if the
voltmeter does not read 2.5 Ohms (± 10%).
7. If the problem still exists, contact the Customer Service Department at
800-331-3578.
