1. Disconnect the high voltage cable from Terminal B of the high-voltage supply
board.
2. Attach a voltmeter to the terminal.
3. If there is no output from the terminal, replace the high voltage power supply.
-or-
1. If there is output from the terminal, test the resistance between the high voltage
cable and the ground.
2. If resistance is "0" or nearly "0", check the high-voltage harness for defects and
replace it if necessary.
3. If replacing the harness does not solve the problem,
4. Test the resistance between the development unit terminal and the ground. If there
is no resistance (0
Ω
) between the development unit and the ground, replace the
development unit.
5. If there is no development PWM signal, replace the harness and/or IOB.
