BATTERY EQUALIZER OWNER’S MANUAL 13
12. If the voltage drops below the calculated value from Step 9 and the clamp-on ammeter has not
jumper from approximately 0 to more than 3 amps of current wait for an additional 30 seconds.
13. If the equalizer does not turn ON after 30 seconds the unit is defective and should be sent in for
repair.
Test Procedure for Family 3, 4 & 5 Battery Equalizers
Models 60-60, 60-80 and 60-100 Models 65-60, 65-80, 65-100
Models 66-60-66-80, 66-100
General : Family 3, Family 4 and Family 5 Equalizers contain an indicator light. If the indicator light is ON
the equalizer is working.
The Equalizer is working properly if:
1. The Indicator Light is ON and;
2. The 12 volt DC loads are being operated continuously and are within the rated capacity of the
equalizer and;
3. Battery A voltage is lower than Battery B by no more than 0.05 to 0.10 volts (measured at the
equ24, +12 and GND terminals).
Family 3, 4 and 5 Battery Equalizers are electronically protected against reverse polarity damage
therefore the DC connection sequence is not an issue.
Family 3, 4 and 5 Equalizers will not function properly unless all three battery connections are made.
Battery A and Battery B voltages both must be above 8 volts for the unit to turn ON.
Any combination of Family 1, Family 3, Family 4 and Family 5 models may be operated in parallel.
Please note that the 24V, 12V and GND stud position and orientation are different on Family 3, 4 and 5
models than on Family 1 or Family 2 models.
Family 3, Family 4 and Family 5 Battery Equalizer Test Procedure:
1. Field test the equalizer while fully connected to the vehicle batteries. For bench testing, two 12 volt
batteries, or two 12 volt power supplies are required. Family 3, 4 and 5 Equalizers must be connected
to the batteries at GND, 12V and 24V to function properly.
2. If battery voltage is below 24 volts start the vehicle or apply a 24 volt battery charger to the batteries.
3. Turn ON 12 volt DC loads up to the equalizer rated capacity. Measure DC amps on the equ12
cable to verify load amperages.
4. At the equalizer measure and record:
a. Battery A voltage (voltage between the equ12 and GND terminals)
b. Battery B voltage (voltage between the equ24 and +12 terminals)
c. Equalizer Indicator Light status (ON or OFF)
