• Inspect the gun handle power supply cavity for dirt

or moisture. Clean with a clean, dry rag.

• Do not expose gasket (28) to solvents.

NOTICE

NOTICE

NOTICE

Be careful when handling the power supply
(11) to avoid damaging it.

3.

Grasp the power supply (11) with your hand.
With a gentle side to side motion, free the power
supply/alternator assembly from the gun handle
(16), then carefully pull it straight out.

On Smart

Models only,

disconnect the flexible circuit (24)

from the socket at the top of the handle.

4.

Inspect the power supply and alternator for
damage.

5.

To separate the power supply (11) from the
alternator (15), disconnect the 3-wire ribbon
connector (PC) from the power supply.

On Smart

Models only,

disconnect the 6–pin flexible circuit

(24) from the power supply. Slide the alternator
up and off the power supply.

6.

Follow the steps in

Test Power Supply Resistance, page 48

Replace the power supply if necessary.
To repair the alternator, see

Alternator Removal and Replacement, page 67

NOTICE

NOTICE

NOTICE

To prevent damage to the cable and possible
interruption of the ground continuity, bend the
alternator’s 3-wire ribbon cable (PC) upward
and back, so the bend faces the power supply
and the connector is at the top.

7.

Smart models only:

connect the 6–pin flexible

circuit (24) to the power supply.

8.

Connect the 3-wire ribbon connector (PC) to the
power supply. Tuck the ribbon forward, under
the power supply. Slide the alternator (15) down
onto the power supply (11).

9.

Insert the power supply/alternator assembly in
the gun handle (16). Make sure the ground strips
(EE) make contact with the handle. On Smart
models, align the connector of the 6–pin flexible
circuit (24) with the socket (CS) at the top of the
handle. Push the connector securely into the
socket as you slide the power supply/alternator
assembly into the handle.

Figure 43 Connect Flexible Circuit

10. Make sure the gasket (28*), ground spring

(18), and power supply spring (11a) are in
place. Replace gasket (28*) if damaged.
Assemble the barrel (1) to the handle (16). See

Barrel Installation, page 65
