Condition |
Possible cause |
Correction / reference item |
Generator does not charge | Open- or short-circuited lead wires, or loose lead connections. | Repair, replace or connect properly. |
Short-circuited, grounded or open generator coil. | Replace | |
Short-circuited or punctured regulator/ rectifier. | Replace | |
Generator does charge, but charging rate is below the specification | Lead wires tend to get short- or opencircuited or loosely connected at terminals. | Repair or retighten. |
Grounded or open-circuited generator coil. | Replace | |
Defective regulator/rectifier | Replace | |
Defective cell plates in the battery. | Replace the battery | |
Generator overcharges | Internal short-circuit in the battery. | Replace the battery |
Damaged or defective regulator/rectifier | Replace | |
Poorly grounded regulator/rectifier | Clean and tighten ground connection. | |
Unstable charging | Lead wire insulation frayed due to vibration, resulting in intermittent shortcircuiting. | Repair or replace |
Internally short-circuited generator. | Replace | |
Defective regulator/rectifier | Replace | |
Battery overcharges | Faulty regulator/rectifier. | Replace. |
Faulty battery | Replace. | |
Poor contact of generator lead wire coupler. | Repair. | |
Battery runs down quickly | Trouble in charging system | Check the generator, regulator/rectifier and circuit connections and make necessary adjustments to obtain specified charging operation. |
Cell plates have lost much of their active materials a result of overcharging | Replace the battery and correct the charging system. | |
Internal short-circuit in the battery | Replace the battery | |
Too low battery voltage. | Recharge the battery fully. | |
Too old battery. | Replace the battery. | |
Battery “sulfation” | Incorrect charging rate. (When not in use battery should be checked at least once a month to avoid sulfation.) | Replace the battery |
The battery was left unused in a cold climate for too long. | Replace the battery if badly sulfated |
Be extra safety-conscious on bad weather days
Riding on bad weather days,
especially wet ones, requires
extra caution. Braking distances
increase on a rainy day. Stay off
the painted surface marks, manhole
covers, and greasy-appearing
areas, as they can be
especially slippery. Use extra caution
at railway crossings and on
metal grating ...
Starter clutch inspection
Refer to “starter clutch removal and installation” .
Starter clutch
Install the starter driven gear onto the starter clutch.
Turn the starter driven gear by hand to inspect the
starter clutch for a smooth movement. The gear
turns in one direction only. If a large resistance is felt
...
Piston and piston ring inspection
Refer to “piston ring removal and installation” .
Piston diameter
Measure the piston diameter using the micrometer at 15
mm (0.6 In) “a” from the skirt end. If the piston diameter
is less than the service limit, replace the piston.
Special tool
