Powerboostä Iiie Voltage Regulator Test Procedure - Kohler 15CCO Service Manual

PowerBoostä IIIE Voltage
Regulator Test Procedure
1. Disconnect P10 of wiring harness from connector
on voltage regulator. (See Figure 7-1.)
2. Connect components as shown in Figure 7-3.
3. Turn variable transformer setting to zero. Plug in
variable transformer.
4. Turn variable transformer on. Slowly increase
variable transformer voltage to 100 volts. The
lamp should go on between 30 to 40 volts up to
100 volts. If the lamp does not light, turn the

voltage adjustment pot clockwise. If the light still
does not go on, the voltage regulator is defective
and should be replaced. This would correspond to
a low- or no-voltage output condition.
5. Slowly increase voltage to 120 volts. The lamp
should go out and stay out as voltage is further
increased. If the lamp does not go out, turn the
voltage adjustment pot counterclockwise. If the
light still does not go out, the voltage regulator is
defective and should be replaced. This would
correspond to a high voltage output condition.
6. Turn variable transformer to zero and unplug AC
cord.
