Section 07. Flywheel Charge Windings
07.1 CHARGE WINDINGS
One of two types of charge windings may be fitted
to TS and TR engines.
1. Syncro - TS and TR up to, but not on, the engine
numbers shown.
2. Nicsa - TS and TR first fitted on the following
engines:
41 00433 TS1
41 00240 TR1
41 01651 TS2
41 00281 TR2
41 01568 TS3
41 00301 TR3
The Syncro and Nicsa charge winding components
are not interchangeable.
The flywheel charge winding system comprises of
three components: a stator. rotor and regulator.
The rotor, in the form of permanent magnets, is
attached to the back of the flywheel.
The stator consists of coils of copper wire wound
onto a laminated iron core which is attached to the
main bearing housing.
The stator output leads pass through the flywheel
housing to the regulator unit which is attached to the
outside of the housing. Should any of the output cables
be attached to the wrong terminal the regulator unit
will be permanently damaged when the battery is
connected into the circuit.
Battery Charge Indicator Light
Some engines may be fitted with an impulse
transmitter and warning light to provide an indication
of when the system is faulty. The transmitter is fitted
between the rectifier/regulator and the battery, during
periods of running the indicator light will remain unlit
unless there is a fault in the charging system.
The battery charge indicator light will always be lit
to indicate a charging fault. The light will also be
switched on with a fully serviceable system under
the following circumstances:
a. If the charge rate drops below 2 Amps at normal
engine speed and the battery is fully charged.
b. The charge rate drops below 4 Amps at idling
speed.

Fault Finding
The most common faults associated with this
system are dealt with in the flow charts.
In cases where no electric start is possible
reference should firstly be made to 'Starter Motor.
Battery and Charge System Fault Diagnosis 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 necessary instruments and connection diagram
to carry out the tests are given in "Nicsa
Charge Windings".
