Charging System – V6 Page 6D1-1-10

3 Minor Service Operations
3.1 Safety Precautions
Observe the following precautions. Failure to observe these precautions will result in serious damage to the generator.
• Only use the generator and voltage regulator in a negative ground system.
• Always refer to 1.2 W ARNING, CAUTION and NOTES before disconnecting the battery.
• W hen installing a battery, fit the positive (+) cable to the battery before fitting the negative cable.
• W hen a slave battery is used for starting purposes, ensure that both batteries are connected in parallel. That is,
positive terminals connected and negative terminals connected.
• Only use jumper leads that have surge protection.
• Disconnect both battery cables when charging the battery. This isolates the generator from the battery and from
the external charging equipment.
• Do not operate the generator within an open circuit or without a battery in the circuit.
• Do not disconnect the battery while the generator is running.
• Do not attempt to polarise the generator.
• Do not connect generator connector E-4 pin 1 to 12 V (the battery or ignition circuits).
• Some battery powered timing lights can produce high transient voltages when connected or disconnected.
Only disconnect or connect timing lights when the engine is switched off.

Ensure the generator connector E-4 pin 1 has
a maximum sinking current of 50mA.
3.2 Maintenance
Regular Checks
Check the following at regular intervals:
• generator terminals – for corrosion and loose connections,
• wiring – for continuity and damaged insulation,
• mounting bolts – for tightness,
• drive belt – for alignment and wear, and
• drive pulley – for damage and warping.
NOTE
The drive-belt adjustment for the engine
ancillaries (i.e. generator and water pump) is
provided by a spring-loaded tensioner. Therefore,
the drive belt does not require manual
adjustment.
Lubrication
High tolerance bearings are used in this generator. If the bearings are removed during the generator disassembly, new
bearings must be installed to restore the generator to original specification. The ball bearings supporting the rotor shaft
are pre-lubricated and sealed. Do not attempt to lubricate these during servicing.
