replacing the upper circuit board or wiring harness.
The checks are to be done with the wiring harness
REMOVED from the lower circuit board, and the
OFF-ON switch turned to "ON".

NALS OR DAMAGE TO THE BOARD WILL
RESULT.
Before any checks are to be done, be sure proper
DC volts are to the board (see Sec.
3.1). Measure volts between yellow
terminal on the 6-pin connector (posi-
tive [+] lead from meter) to green
terminal on 6-pin connector (negative [–
] lead from meter). Voltage should be
the same as at the positive (+) and
negative (–) terminal block. If not,
check the fuse (see Sec. 4.11) and
wiring (see Sec. 7.2).
