Test Procedure.
NOTE: Do not remove or install wires while timer board

damage to the board.
1. Disconnect the brewer from the power source and
remove the front access panel.
2. Remove the two #8-32 screws securing circuit
board to the mounting bracket.
3. Remove circuit board and spacers (as required).
4. 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, three

els.
b) 200 to 240 volts ac on two wire 200 volt or 240
volt models.

If voltage is present as described, proceed to #6.
If voltage is not present as described, refer to the
Wiring Diagrams and check the brewer wiring har-
ness.
