2. Disconnect the white connector and the
whitehed lead from the regulator (Figure 26).
The whitehed lead is "hot." Do not short
circuit the voltage regulator when
connecting the test leads.
3. With an ohmmeter set at RxlO or Rx100,
measure the resistance between each yellow
lead and the whitehed lead, then between each
yellow lead and the black lead. Keep the same
meter lead on the whitehed and the black
leads, in turn. Note the readings.
4. Reverse the meter polarity (use the opposite
probes to make the connections) and repeat the
tests. There should be more than 10 times as
much resistance in one direction as in the
other. Ifany 2 leads show the same resistance in
both directions, the regulator/rectifier is faulty
and should be replaced.
The stator is mounted inside the left-hand
1. Remove the engine sprocket cover: see
Sprocket Cover Removal in Chapter Six.
2. Disconnect the yellow leads from the
alternator (Figure 25).
3. Remove the 4 alternator cover screws and
the cover and gasket (Figure 27). There are 2
locating dowel pins.
4. To remove the stator coils from the cover,
remove the 3 coil Allen bolts and the wire guide
screws (Figure 28).
5. T o install, reverse the removal steps. Note
a. Use a locking agent such as Loctite Lock
N' Seal on the stator coil Allen bolts.
b. Make sure the 2 cover dowel pins are in
place (A, Figure 29).
The alternator rotor is mounted on the
left-hand end of the crankshaft. Rotor
replacement is usually necessary only if the
rotor magnets have been damaged by
mechanical shock or heat. The rotor can be
removed after removing the alternator
