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 |
