IN-VEHICLE TESTING
Equipment needed: Multimeter or voltmeter.
5W/24V test lamp with connection leads/clips.
• Leave input (VIOLET) wire and earth (GREEN) wire connected.
• Disconnect output (BROWN) wire from battery. (Do not allow BROWN wire to contact chassis/earth).
• Connect 5W test lamp between BROWN wire and vehicle chassis/earth.
• The lamp should light up.
• Using a voltmeter, measure voltage on the BROWN wire. (Voltmeter positive wire to BROWN wire,
negative wire to chassis/earth)
• Measure voltage on the input (VIOLET) wire 24V connection. (Voltmeter positive to VIOLET wire
connection, negative to chassis/earth)
• Voltage on BROWN wire should be half the voltage on the VIOLET wire. (within 0.25V)
Example 1.
With Motor running, if VIOLET wire measures 28V, BROWN wire should be 14V (+/- 0.25V), i.e. BROWN
wire voltage should be in range 13.75V to 14.25V.
Example 2.
With Motor not running, if VIOLET wire measures 24V, BROWN wire should be 12V (+/- .25V), i.e. BROWN
wire voltage should be in range 11.75V to 12.25V.
If these voltages are OK, it indicates the Charge Equaliser is operating correctly.
If 12V battery does not maintain the correct voltage, check that all connections are sound. If this is all OK,
measure the 12V current draws and check that the Charge Equaliser is suitably rated.

Equipment Circuit Breaker rating is dependant
on the total load rating of all the equipment used.
Fuses may be used however self resetting
circuit breakers are recommended.
