When a lack of high voltage at the spray gun
indicates a problem, a kV Output Test of the
Power Supply may be performed to help deter-
mine whether it is at fault.

1. Turn AC power to the power supply
OFF
OFF OFF OFF OFF.
2. Remove the high voltage (HV) cable
from the power supply.
3. Open the cabinet door and position
jumper JP4 on the main PC Board so
that it covers (shorts) both terminals.
! Whenever removing high voltage cables
from equipment, ground the plug end of the
cable(s) by contacting the plug to electrical
ground. DO NOT
DO NOT DO NOT DO NOT DO NOT touch the plug until it has
been grounded. This will eliminate the
possibility of residual charge causing electri-
cal shock.

4. Attach the appropriate HV cable to the
Test Probe (76652-01), properly ground
the probe to a true earth ground and turn
the Test Probe Meter on (see Operation
Manual of 76652-01 Tester).
5. Insert the Test Probe HV cable into the
Power Supply HV Tube until it bottoms
out.
6. Turn the power supply ON ON ON ON ON.
7. Read the output voltage displayed on the
meter, then turn the power supply OFF.
If the voltage DOES READ
DOES READ DOES READ DOES READ DOES READ correctly
(see "Specifications" in the "Introduction"
section of this manual), the problem is
not in the Power Supply, therefore the
HV Cable and spray gun should be
checked for the cause. If the voltage
DOES NOT READ
DOES NOT READ DOES NOT READ DOES NOT READ DOES NOT READ correctly, the
problem is with the power supply. Con-
sult the "Troubleshooting Guide" (Figure
9) to locate the specific problem.
8. Disconnect the Test Probe (76652-01)
and reposition JP4 so that it covers only
one terminal. When ready to resume
spray operations, reconnect the spray
gun HV cable and turn the power supply
on.
! Ensure that the Test Probe HV cable
makes good contact both inside the Test
Probe and inside the Power Supply HV
Tube.
