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 |
Battery runs down quicklyEngine coolant solution
Use engine coolant that is com·
patible with an aluminum radiator,
mixed with distilled water at a
50:50 mixture ratio for engine
coolant solution. An engine coolant
mixture other than 50:50 can
affect cooling efficiency or rust
inhibiting performance.

Cylinder head related parts inspection
Refer to “cylinder head disassembly and assembly” .
Cylinder head distortion
Decarbonize the combustion chambers.
Check the gasket surface of the cylinder head for
distortion. Use a straightedge and thickness gauge.
Take clearance readings at several places. If
readings exceed the ...
Precautions
Precautions for engine cooling system
You can be injured by boiling fluid or steam if you open the
radiator cap when the engine is hot.
After the engine cools, wrap a thick cloth around cap and carefully
remove the cap by turning it a
quarter turn to allow pr ...
