2/12/75A Battery Charger/Starter
Possible Cause(s)
The charger reached
the maximum voltage
and is reducing the
current.
1. Extension cord is
too long or wire
gauge is too small.
2. Weak cell or
sulfated plate in
battery.
3. Battery is partially
discharged.
1. Transformer
laminations vibrate
(buzz).
2. Shorted Diode
Assembly or
Output.
3. Rectifier Assembly
(hum).
1. Circuit breaker is
cycling.
2. Battery is defective.
3. Shorted battery
cables or clips.
4. Severely discharged
battery, but
otherwise it is a
good battery.
5. Reverse
connections at
battery.
Suggested Solution(s)
No problem, this is a normal condition.
1. Use a shorter or heavier gauge
extension cord.
2. A sulfated battery will eventually take a
normal charge if left connected. If the
battery will not take a charge, have it
checked.
3. Continue to charge the battery.
1. No problem, this is a normal condition.
2 & 3. Have charger checked by a
qualified technician.
1. The settings may be wrong. Check the
charger settings.
2. Have the battery checked.
3. Circuit breaker cycles when current
draw is too high. Check for shorted
cables or clips and replace if necessary.
4. The battery may not want to accept a
charge due to a run-down state. Allow
charging to continue until battery has a
chance to recover sufficiently to take a
charge. If more than 20 minutes, stop
charging and have the battery checked.
5. Shut the charger off and correct the
lead connections.
