Generator Testing
The following table will apply in checking the
alternator outputs and the readings should be taken
only under loaded conditions as detailed in column 3
and column 4. The table embraces values associated
with the lights, horn and stop light circuits. The
ignition feed coil is dealt with separately. The
voltmeter used in these tests should be a good quality
moving coil instrument and the 1 ohm resistance must
be accurate otherwise correct results cannot be
obtained. With respect to column 3, the light should,
of course, be switched on before checking these output
figures and care should be taken to see that the correct
bulbs are fitted with in the lamps at the time of testing.
When testing in accordance with column 4, be sure the
lighting witch is in the "off" position.
Ignition Feed Coil
The ignition feed coil operates between the maroon
and translucent (earth) lead. A useful check in the case
of misfiring is to start the machine and check between
the maroon lead at the four-hole connector and earth.
At 3,000 r.p.m., nine volts should be attained. Where a
machine will not start, a test can be made by
unplugging the maroon lead from the four-hole
connector and checking with the voltmeter between
the maroon lead and earth. At kick-over,
i.e.,
approximately 1,000 r.p.m., the meter will read 4·5—
5·0 volts. The resistance of the feed coil is 1·85 ohms.
