8.1 Introduction (Cont.)
8.1.3 Troubleshooting the 10-point Terminal Board
The 10-point terminal board is mounted on a bracket located in the right front corner of the
machine base. The terminal board provides easy access for making voltage checks to most
of the electrical components mounted on the base of the machine.
Voltages are measured between a numbered wire and common (#2).
All voltages are control voltage and should read approximately 120VAC.
120VAC should be present at the terminal if the associated LED on the
board is illuminated.
For example:
If the Drain LED is illuminated on the Timer Control Board, then 120VAC
should be present between Wire #54 and Wire #2.
