Battery Status LEDs
Connected (red LED) – Indicates that the charger is
properly connected to the battery.
• If the charger does not detect a properly
connected battery, the CONNECTED LED will
not light. Charging will NOT begin if the
CONNECTED LED is not on.
Charging (yellow LED) – Indicates the charger has
detected a battery and is charging it.
Charged (green LED) – Indicates the battery is
fully charged and the charger is in maintain mode.
• Completion of Charge is indicated by the
CHARGED LED. When lit, the charger has switched to the Maintain Mode of operation.
• MaintainMode (Float-Mode Monitoring) – When the CHARGED LED is lit, the charger has started
Maintain Mode. In this mode, the charger keeps the battery fully charged by delivering a small
current when necessary.
Modes
• AbortedCharge– If charging cannot be completed normally, charging will abort. When charging
aborts, the charger’s output is shut o and the digital display will show a failure code (see the
TROUBLESHOOTING section for a description of the failure codes). In that state, the charger ignores
all buttons. To reset after an aborted charge, turn the Function Control switch to the OFF (O)
position. Then place the Function Control switch back in the previous position and reset all of the
controls to the desired settings.
NOTE: If the charger has to provide its maximum maintain current for a continuous 12-hour period,
it will go into Abort Mode (see Aborted Charge, above). This is usually caused by a drain on the battery, or
the battery could be bad. Make sure there are no loads on the battery. If there are, remove them. If there are
none, have the battery checked or replaced.
• DesulphationMode–If the battery is left discharged for an extended period of time, it could
become sulphated and not accept a normal charge. If the charger detects a sulphated battery,
the charger will switch to a special mode of operation designed for such batteries. If successful,
normal charging will resume after the battery is desulphated. Desulphation could take up to
8 hours. If desulphation fails, charging will abort, and the digital display will show a failure code
of F02 (Bad Battery).

• MaintenanceMode–(2AmpChargeRate)– The 011-1586-4 is a battery charger with a
maintenance setting that maintains 12 V batteries, keeping them at full charge. On this setting, it
can charge small batteries and maintain both small and large batteries. If you are maintaining a
fully charged large battery, you will be properly utilizing the maintenance setting. However, if you
were to use the maintenance setting to charge a large battery, such as a marine deep cycle battery,
that was not fully charged, you may lose some of the battery’s capacity. This would cause the large
battery to be unable to hold a charge and become useless. Therefore, we do not recommend
charging a large battery on the maintenance setting.
NOTE: The maintain mode technology utilized in MotoMaster Eliminator chargers allows you to safely
charge and maintain a healthy battery for extended periods of time. However, problems with the battery,
electrical problems in the vehicle, improper connections or other unanticipated conditions could cause
excessive current draws. As such, occasionally monitoring your battery and the charging process is
recommended.
Voltage Tester
Overview – This battery charger has a built-in voltmeter to test your battery’s state of charge.
The charger does not have a built-in load tester. As such, a recently charged battery could have a
temporarily high voltage due to what is known as “surface charge”. The voltage of such a battery will
gradually drop during the period immediately after the charging system is disengaged. Consequently,
the tester could display inconsistent values for such a battery. For a more accurate reading, the surface
charge should be removed by temporarily creating a load on the battery, such as by turning on lights
or other accessories for a couple of minutes before you read the display. Read it a couple of minutes
after you have shut the headlights o.
Testing Sequence – There are ve basic steps required to test the battery state of charge:
1. With the charger unplugged from the AC outlet, connect the charger to the battery following the
instructions given in Connecting Your Battery.
2. Plug the charger’s AC power cord into the AC outlet, following the instructions given in Charging
Your Battery.
3. Place the Function switch in the down (20/2 A) position.
4. Make sure the LED on the timer is next to the OFF (O) position.

Alternator Performance Tester
Overview – This battery charger has a built-in alternator tester that displays an estimate of the
alternator’s relative output compared to normal alternators. The alternator percentage values
displayed should be taken as a general reference, not a precise diagnosis. The alternator tester
functions like the built-in battery voltage tester (see previous section for details) with a few dierences.
Testing Sequence – There are ve basic steps required to operate this unit as an alternator tester:
1. With the charger unplugged from the AC outlet, connect the charger to the battery following the
instructions given in Connecting Your Battery.
2. Plug the charger AC power cord into the AC outlet, following the instructions given in Charging Your
Battery.
3. Place the Function switch in the down (20/2 A) position.
4. Make sure the LED on the timer is next to the OFF (O) position.
5. Start the vehicle and turn on the vehicle’s headlights. Read the voltage on the digital display.

General Charging Notes
Fan – The charger is designed to control its cooling fan for ecient operation. Consequently, it is
normal for the fan to start and stop when maintaining a fully charged battery. The fan does not
run in Tester Mode. Keep the area near the charger clear of obstructions to allow the fan to operate
eciently.
Restart – If the Charge Mode is changed after charging has started (by pressing the CHARGE RATE
button), the charging process will restart.
