Location:
The timer is located inside the front of the trunk on
the component bracket. It consists of the dial plate and
circuit board.
Test Procedure:
1. Disconnect the brewer from the power source.
2. Remove the wires from terminals TL3, TL4, & TL5
of the timer and rotate the dial fully counterclock-
wise.
2. With a voltmeter, check the voltage across termi-
nals TL1 and TL2 when the ON/OFF switch is in the
“ON” (upper) position. Connect the brewer to the
power source. The indication must be 240 volts ac.
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
Wiring Diagram and check the wiring harness.
4. Check for continuity across the white/orange wire
and white/yellow wire when the START switch is
held in the lower position.
If continuity is present as described, reconnect the
wires to terminals TL3, TL4, & TL5 of the timer board
and proceed to #5.
