TROUBLESHOOTING
5. Measure VDC between test points 7 and 12 of the power control
board for a minimum of 6.0 VDC.
6. Test pins 1 and 7 of the main cable at the console connection for a
minimum of 6.0 VDC.
7. Reconnect the main cable to the console.
8. Verify that the inductive switch is adjusted to within 1/32" (0.8 cm) of
the speed sensor disk on the front of the alternator.
9. Unplug the inductive switch cable from the power control board and
test pins 1 and 2 for AC voltage while pedaling. VAC should increase
with RPM.
10. Plug the inductive switch back in. Use a voltmeter to verify that the AC
voltage at pins 10 and 12 of the power control board increases when
RPM's increase (pin 10 is positive, pin 12 is negative).
11. Unplug the alternator wiring connector from the power control board.
12. Connect alligator clips between the B+ terminal and the FLD terminal
of the alternator.
13. Pedal the cycle at a high RPM rate for 10-15 seconds or until you feel
the resistance level change making it harder to pedal.
14. Unplug the diode from the FLD terminal of the alternator.
15. Use a voltmeter, set to Ohms to test the diode. A good diode will show
a high resistance reading in one direction and a low resistance
reading when the voltmeter leads are reversed.
16. Reconnect the diode to the FLD terminal of the alternator.
17. Reconnect the alternator wiring connector to the power control board.
18. Unplug the load resistor from the power control board and locate pin
1 and pin 2 at the end of the cable.
