• Turn the power off.
• Disengage the
brake.
• Remove the white wire from the B+ terminal on the alternator.
• Remove the brown wire from the field (FLO) terminal on the
alternator.
• Place alligator clips on the
alternator.
• Step on the machine for 15 - 20 seconds.
• If res istance is ach ieved during this

13. Unplug the diode from the FLO terminal of the
14.
Use a multimeter 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 multimeter leads are reversed
15.
Unplug the load resistor from the power control board. Set your multimeter
to
ohms.
Insert the multimeter leads into the load resistor plug.
16.
A load resistor in proper working condition should read approximately 0.5
ohms.
If the number recorded is outside the specified range, replace the
load
resistor.
17.
Check the ma in cable assemblies for continuity, and cross check each wire
in the cables for shorted wires (see Figure 35).
