ELECTRICAL EQUIPMENT
Alternator checking (stator)
Disconnect alternator cables from the regulator and check
continuity between the windings with an Ohmmeter.
Also check that there is good insulation between cables and
earth (fig. 45). In the event of an open circuit, replace the
stator. If the stator is in good working order but the values of
the alternator charge are lower than those stated, the rotor is
demagnetised and the entire alternator must be replaced.
Method of use
By turning the starter key to the first position, the battery charging
circuit is started off, and thus:
1.With engine stationary the key must be kept on the off position.
If it is left on the first position, the oil warning light could burn
out, the battery could discharge and the regulator could be
damaged.
2.With engine running turn key to first position. If it is left in the off
position, the oil warning light and battery charging functions are
excluded.
The voltage regulator will be damaged beyond repair, if it
is run with the battery cables disconnected or with
unactivated batteries.
Wire checking
Examine condition of wires bearing the following in mind:
1.With one of the yellow wires open circuited, the alternator will
not supply current for the 12V/280W and will only supply half
current for the 12V/210W.
2.With both yellow wires open circuited, the alternator will not
supply current at all.
3.With one or both wires earthed, the rotor will demagnitize very
quickly and the coils of the stator will burn out.
4.With red wire open circuited, the alternator will not supply
current.
5.With red wire earthed the alternator will not supply current, the
connection wires and warning circuit will burn out and the
battery will discharge completely.
6.Avoid sparks between cables, as the alternator could burn out.
7.With an imperfect earth between the negative battery terminal
and regulator casing, the charging current is irregular and the
regulator could be damaged.
8.If the battery connections are inverted, the alternator and
regulator will burn immediately.
