50 Section 5 Component Testing and Adjustment

Hazardous voltage.

Will cause severe injury or death.

This equipment must be installed and

serviced

qualified

electrical

personnel.

DANGER

Testing live electrical circuits. Hazardous voltage or

current can cause severe injury or death.

Have trained and

qualified personnel take diagnostic measurements of live

circuits. Use adequately rated test equipment with electrically

insulated probes and follow the instructions of the test

equipment manufacturer when performing voltage tests.

Observe the following precautions when performing voltage

tests: (1) Remove all jewelry. (2) Stand on a dry, approved

electrically insulated mat. (3) Do not touch the enclosure or

components inside the enclosure. (4) Be prepared for the

system to operate automatically.

(600 volts and under)

Short circuits. Hazardous voltage/current can cause

severe injury or death.

Short circuits can cause bodily injury

and/or equipment damage

Do not contact electrical

connections with tools or jewelry while making adjustments or

repairs. Remove all jewelry before servicing the equipment.

Separate Excitation Procedure

Perform the following procedure to use an external

voltage source to excite the main field (rotor).

1. Disconnect the black FN and FP leads from the

alternator at the SCR module (+) and (--) terminals.

2. Connect a DC ammeter, 10-amp fuse, and a

12-volt automotive battery to the positive (FP) and

negative (FN) brush leads as shown in Figure 5-3.

Note and record the ammeter reading.

Note:

The approximate ammeter reading should

be the battery voltage divided by the

specified rotor resistance. See Section 1,

Specifications, for specified rotor resistance

values.

Example:

12 volts (battery voltage)

3.0 ohms (rotor resistance)

4.0 amps

(rotor current)

3. Start the engine and check that the ammeter

reading remains stable. An increasing meter

reading indicates a shorted rotor. A meter reading

decreasing to zero or an unstable reading

suggests a running open. Refer to Section 5.4,

Main Field (Rotor), to test the rotor. If the ammeter

reading is stable, proceed to step 4.

4. Check for AC output across the stator leads; see

Section 5.3, Stator. Compare the readings to the

output

values

shown

Section 1,

Specifications. If the readings vary considerably, a

faulty stator is likely. Refer to Section 5.3, Stator,

for further information.

5. If this test shows that the rotor and stator are in

good condition, check the wiring and fuses. Check

the SCR module.

See Section 4.7, Silicon

Controlled Rectifier (SCR) Module. Check the

controller settings and connections.

See

Section 4, Controller.

Separate Excitation Connections

5.3 Stator

The stator contains a series of coils of wire laid in a

laminated steel frame. The stator leads supply AC

voltage to the load and voltage regulator. Before testing

the stator, inspect it for heat discoloration and visible

damage to housing lead wires, exposed coil windings,

and exposed areas of frame laminations. Be sure the

stator is securely fastened to the stator housing.

Note:

Disconnect all stator leads before performing all

stator tests.
