External Meter Test
1. This method uses the test assembly (76652-
02 or 76652-04). It must be used if the power
supply DOES NOT have a microampmeter.
2. Remove the bell from the gun. Connect one
of the alligator clamps of the test meter to the
contact brush and the other to ground.
3. Set the switch on the test meter to µA (mi-
croamperes).
4. Turn the power supply ON.
5. Activate the motor circuit at the gun. The
test meter reading should be approximately 80
to 115 microamperes.
Power Supply Meter Test
1. This method uses the microampmeter located
on the power supply.
2. Remove the bell from the gun. Rotate the
contact brush outwards and touch the contact
brush to ground.
3. Turn the power supply ON.
4. Activate the motor circuit at the gun. The meter
of the power supply should read approximately 80
to 115 microamperes.

following procedures should be followed:
1. Turn the high voltage “OFF” and disconnect
the AC power to the power supply.
† High voltage components, such as ca-
ble and high voltage resistor, are not field
serviceable. For repair or replacement of
such items, contact your Ransburg dis-
tributor.
† BEFORE attempting any cleaning or col-
or change procedures the high voltage and
the AC power to the power supply MUST be
turned OFF!
2. Flush the fluid line and gun with a suitable
solvent.
3. Loosen the set screw on the bell hub, remove
