If continuity is present as described, reconnect the
wires to terminals TL3, TL4, & TL5 of the timer board
and proceed to #5.
If continuity is not present as described, refer to the
Wiring Diagrams
and check the wiring harness.
5. With a voltmeter, check the voltage across termi-
nals TL1 and TL4 when the ON/OFF or selector
switch is in the "ON" (T3 left, T6 left or right) po-
sition and the start switch is momentarily placed
in the lower position. Connect the brewer to the
power source. After a delay of approximately three
minutes, the indication must be:
a) 120 volts ac for two wire 120 volt models for
approximately one minute and then return to its
previous indication.
b) 240 volts ac for two wire 240 volt models for
approximately one minute and then return to its
previous indication.
c) 100 volts ac for two wire 100 volt models for
approximately one minute and then return to its
previous indication.
6. Disconnect the brewer from the power source.
If voltage is present as described, the timer is operat-
ing properly. Adjust the timer dials as required.
If voltage is not present as described, replace the timer.
Removal and Replacement:
1. Remove all wires from the timer.
2. Remove the circuit board and dial plate from the
brackets.
4. Install the new dial plate and circuit board to the
brackets.
5. Refer to Fig. 12 when reconnecting the wires.
6. Adjust the timer dials as required.

Location:
The dilution timer is located inside the hood on the
right side. It consists of the dial plate with two dials
and circuit board.
Test Procedure:
1. Disconnect the brewer from the power source and
remove the wires from terminals TL3, TL4, & TL5
of the timer and rotate both dials fully counter-
clockwise.
2. With a voltmeter, check the voltage across termi-
nals TL1 and TL2 when the ON/OFF switch is in
the "ON" position. Connect the brewer to the power
source. The indication must be:
a) 120 volts ac for two wire 120 volt models.
b) 240 volts ac for two wire 240 volt models.
c) 100 volts ac for two wire 100 volt models.
3. Disconnect the brewer from the power source.
If voltage is present as described, proceed to #4.
If voltage is not present as described, refer to the
Wir-
ing Diagrams
and check the wiring harness.
4. Check for continuity across the green and red/
black wires when the start switch is held in the
lower position.
