55.
1. Undo the bolts shown fixing the alternator
assembly.
2. Dismantle the following alternator com­
ponents:
A. Rear support plate with stator wind­
ings
B. Rotor
C. Front support plate
3. Checking inductor (rotor) winding re­
sistance at the slip rings
- Place the two probes of an ohmmeter (set
on a scale of Q x 1) in contact with the ro­
tor slip rings (shown by the arrows): the in­
strument reading should show a certain re­
sistance value.
NOTE If the resistance value is infinite
(broken circuit)rrotto), then the ro­
tor has to be replaced.
4. Checking stator winding insulation
- Place the two probes of an ohmmeter (set
on a scale of Q x 1) in contact with the
windings and the stator casing, respective­
ly;
- the resistance reading on the instrument
should be infinite, if this is not the case re­
place the rotor.
