Engine Board Disconnect the solenoid/input sensor cable from
CN3 on the engine board. Check the voltage at
CN3-5. The voltage should measure approxi-
mately +24 V dc. If incorrect, replace the engine
board.
If the voltage reads approximately +24 V dc,
check the voltage at CN3-6 while running a test
page. The voltage should measure 0 V dc and
read approximately 1 V dc at the time the sole-
noid should pick. If incorrect, replace the engine
board.
