FIG. 20 TIMER TERMINALS
Location:
The timer is located inside the front of the trunk on
the upper right side of component bracket.
Test Procedure.
1. Disconnect the brewer from the power source.
2. Disconnect the polarized, three pin connector from
the brewer wiring harness and rotate the brew
timer dial fully counterclockwise.
3. With a voltmeter, check the voltage across sockets
P2 & P3 (white and black wires) of the female
connector when the "ON/OFF" is in the "ON" (upper)
position. Connect the brewer to the power source.
The indication must be:
a) 120 volts ac for two wire 120 volt models.
b) 120 volts ac for three wire 120/208 volt and 120/
240 volt models.
4. Disconnect the brewer from the power source.
If voltage is present as described, proceed to #5.
If voltage is not present as described, refer to the
Wiring Diagrams
and check the brewer wiring har-
ness.
5. With a voltmeter, check the voltage across the
sockets P1 & P2 (blue and white wires) of the
female connector when the "ON/OFF" switch is in
the "ON" (upper) position and start switch pressed.
Connect the brewer to the power source. The
indication must be:
a) 120 volts ac for two wire 120 volt models.
b) 120 volts ac for three wire 120/208 volt models
and 120/240 volt models.
6. Disconnect the brewer from the power source.

7. Reconnect the three pin connector from main
wiring harness to the timer.
If voltage is present as described, proceed to #8
If voltage is not present as described, refer to
Wiring
Diagrams
and check the brewer wiring harness.
8. Disconnect the black and white wires to the sole-
noid.
9. With a voltmeter, check the voltage across the
black and white wires when the "ON/OFF" switch is
in the "ON" (upper) position and the "START"
switch is pressed to the "START" (lower) position
and released. Connect the brewer to the power
source. The indication must be:
a) 120 volts ac for approximately 20 seconds for
two wire 120 volt models.
b) 120 volts ac for approximately 20 seconds for
three wire 120/208 volt and 120/240 volt models.
If voltage is present as described, the brew timer is
operating properly. Reset the timer dial as required, to
obtain the desired brew volume.
If voltage is not present as described, replace the
timer.
Removal and Replacement:
1. Remove all wires from the timer.
2. Remove the one #8-32 screw securing timer to
component bracket.
3 Install new timer circuit board as described in
Late
Model Digital Timer
section on the following pages.
4. Refer to Fig. 22 when reconnecting the wires.
5. Install the Timer Setting decal, provided with the
replacement timer kit, to the rear of the front
access panel, beneath the schematic.
5. Adjust the timer as required. Refer to
Late Model
Digital Timer Section
on the following pages.
