ANALOG POWER PC BOARD VOLTAGE TEST (continued)
FIGURE F.14 – ANALOG POWER PC BOARD
TEST PROCEDURE
1. Turn the engine off.
2. Perform the Case Cover Removal proce-
dure.
3. Locate plugs J41 and J42 from the Analog
Power PC board. See Figure F.14.
4. Start the engine and run it at high idle (3700
RPM) with no load.
5. Check for the correct Analog Power PC
board input voltage:
a. Set the volt/ohmmeter to the Volts DC
position.
b. Place the negative probe on J41 pin 2 and
the positive probe on J41 pin 1.
c. The reading should be between 75 and 85
VDC.
If the reading is not correct, the stator output may
be incorrect, the rectifier output may be incorrect,
the capacitors may be faulty or the Power Module
PC board may be faulty. Perform the Stator
Voltage Test, the Output Rectifier Bridge Test,
and the Power Module PC Board Test. The
capacitors C1 and C2 may be faulty. Test and
replace if necessary.
6. Check for the correct output voltage readings
per Table F.1. If any of the readings are not
correct, the Analog Power PC board may be
faulty.
