1. Properly attach connector.
2. Turn signal on and adjust to proper setting.
3. Short PC board jumper JP4. If high voltage
comes on, replace high voltage trigger device
or repair wiring from trigger device to PC board.
4. Replace main PC board.
1. Ensure sufficient distance between spray
applicator and parts.
2. Adjust PC board potentiometer 1 turn counter-
clockwise to make less sensitive. Repeat if
necessary.
3. Disconnect high voltage cable from spray
applicator and test in open air, at least 1-foot
from surrounding objects. If overload goes
away, check spray applicator for cause.

4. Test power supply with high voltage cable
removed. If overload goes away, replace the
high voltage cable.
5. Place PC board jumper JP5 over pins 1 and 2
(overload OFF) and test. If power supply
overloads, replace main PC board.
6. If 1 thru 5 above are OK, replace the high
voltage multiplier.
1. Repair loose or broken wire.
2. Replace component.
