Battery Cable Service

To ensure good electrical contact between the

battery and the electrical cables, the cables must be

clean and free of corrosion.

1. If the electrical cable terminals are badly cor-

roded, disconnect them from the motorcycle’s elec-

trical system.

2. Thoroughly clean each connector with a wire

brush and then with a baking soda solution. Rinse

thoroughly with clean water and wipe dry with a

4

clean cloth.

3. After cleaning, apply a thin layer of dielectric

grease to the battery terminals before reattaching

the cables.

4. If disconnected, attach the electrical cables to the

motorcycle’s electrical system.

5. After connecting the electrical cables, apply a

light coat of dielectric grease to the terminals to re-

tard corrosion and decomposition of the terminals.

shown in A, Figure 8. Do not wait until the battery

is installed, since there is limited working room af-

ter the battery is installed.

3. Inspect the battery case. Look for bulges or

cracks in the case, leaking electrolyte or corrosion

buildup.

4. Carefully check all connections at the alternator

to make sure they are clean and tight.

5. Check the circuit wiring for corroded or loose

6. Inspect the rotor magnets (Figure 20) for small

bolts, washers or other metal debris that may have

19

been picked up by the magnets. These small metal

bits can cause severe damage to the alternator stator

assembly.

7. Check the inner splines (Figure 21) for wear or

damage. Replace the rotor if necessary.

8. Install by reversing these removal steps.

Stator Removal

1. Remove the rotor as described in this chapter.

2. Disconnect the stator electrical connector (B,

Figure 18) from the wiring harness.

NOTE

The following photographs are shown

with the engine removed to better il-

lustrate the steps.

3. Remove the four T27 Torx screws securing the

stator assembly (Figure 22). New Torx screws must

be used on installation.

NOTE

If necessary, spray electrical contact

cleaner or glass cleaner around the

wiring harness grommet to help ease

21

it out of the crankcase boss recepta-

cle.

4. Carefully pull the stator wiring harness and

grommet out of the crankcase boss receptacle (A,

Figure 23) and remove the stator assembly (B).

5. Inspect the stator mounting surface on the crank-

case (Figure 24) for any oil residue that may have

passed by a damaged oil seal. Clean off if necessary.

6. Inspect the stator wires (A, Figure 25) for fray-

ing or damage.

7. Inspect the rubber grommet (B, Figure 25) for

deterioration or hardness.

22

8. Check the stator connector pins (Figure 26) for

looseness or damage.

Stator Installation

1. Apply a light coat of electrical contact cleaner or

glass cleaner to the wiring harness grommet to help

ease it into the crankcase boss receptacle.

2. Insert the electrical harness and grommet into

the crankcase boss receptacle and carefully pull it

CAUTION

New T27 Torx screws must be in-

stalled. The threadlocking compound

originally applied to the Torx screws

is sufficient for one time use only. If a

8

used Torx screw is installed, it can

work loose and cause engine damage.

3. Move the stator into position on the crankcase

and install four new T27 Torx screws. Tighten the

screws to the specifications in Table 6.

4. Connect the stator electrical connector (B, Fig-

25

ure 18) onto the wiring harness.

5. Install the rotor as described in this chapter.

VOLTAGE REGULATOR

Removal/Installation

NOTE

Always disarm the optional TSSM se-

curity system prior to disconnecting

the battery or the siren will sound.

1. Disconnect the negative battery cable from the

battery as described in this chapter.

2. Remove the fuel tank as described in Chapter

Seven.

3. Refer to Electrical Panel in this chapter. Re-

move the cover and outer panel to gain access to the

circuit breaker.

4. Disconnect the voltage regulator black wire

(Figure 28) from the main circuit breaker.

5. Disconnect and remove any cable straps and

clips securing the voltage regulator black wire to the

frame.

IGNITION SYSTEM

The ignition system consists of an ignition coil,

two spark plugs, the ignition module, crankshaft po-

sensor (MAP) and the bank angle sensor (BAS).

The 1999-2000 models are also equipped with the

camshaft position sensor (CMP) that was elimi-
