4. Connect a voltmeter across contacts 2 & 6 of the
larger connector (P4) on the timer board. Plug-in
the grinder. When the control switch is in any posi-
tion except “OFF” (center), the indication must be
120 volts ac for 120V models and 230 volts ac for
230V models.
5. Unplug the grinder.
If voltage is present as described, proceed to #6.
If voltage is not present as described, refer to the
Wiring Diagram
and check the grinder wiring harness.
6. Connect a voltmeter across contacts 3 & 7 of the
larger connector (P4) on the timer board. Plug-in
the grinder. Momentarily press the Off/On/Start
switch to “START” (lower) position and release. The
indication must be 120 volts ac for 120V models
and 230 volts ac for 230V models.
7. Unplug the grinder.
If voltage is present as described, proceed to #8.
If voltage is not present as described, replace the timer.
8. Connect a voltmeter across contacts 4 & 7 of the
larger connector (P4) on the timer board. Plug-in
the grinder. Place the hopper selector switch to
the left position. Momentarily press the Off/On/
Start switch to the “START” (lower) position and
release. The indication must be 120 volts ac for
120V models and 230 volts ac for 230V models
and should remain for the approximate timer set-
ting.
9. Unplug the grinder.
If voltage is present as described, proceed to #10.
If voltage is not present as described, replace the timer.
10. Connect a voltmeter across contacts 5 & 7 of the
larger connector (P4) on the timer board. Plug-in
the grinder. Place the hopper selector switch to
the right position. Momentarily press the Off/On/
Start switch to the “START” (lower) position and
release. The indication must be 120 volts ac for
120V models and 230 volts ac for 230V models
and should remain for the approximate timer set-
ting.
11. Unplug the grinder.
If voltage is present as described, the timer is operat-
ing properly.
If voltage is not present as described, replace the timer.
Removal and Replacement:
