8.3 Nicsa Charge Windings
Fault Finding
The most common faults associated with this system are dealt
with in the flow charts on the following pages.
In cases where no electric start is possible reference should
firstly be made to "Starter Motor, Battery and Charge System
Diagnostic Flow Chart", proceeding through to other charts if
a charge system fault becomes evident.
In cases where a specific charging fault is known to exist refer
directly to the relevant flow chart.
The following instruments are necessary to carry out the
tests.
1.0-20A moving coil ammeter.
2.0-20V moving coil voltmeter or a DC multimeter.
3.0-200V moving iron voltmeter or an AC multimeter.
4.0-5 Ohm meter or multimeter.
