Testing Function
1.
After installing all of the necessary components it is time to test the function of
the system.
2.
With the key off check that both the main and the auxiliary battery have proper
voltage.
3.
Start the car and watch the led indicator on the charging isolator. After a short
delay the charging isolator led will turn on indicating that it is allowing alternator
current to flow to the auxiliary battery. Check this by using a voltage meter to
verify auxiliary battery voltage. Turn the engine off and place the key in the
ignition position without starting the vehicle. Wait one minute and ensure that the
led on the charging isolator is off. If this is the case then the charging isolator is
working correctly and it is now time to check override switch function.
4.
Allow any surface charge to dissipate and using a voltmeter measure the voltage
of each battery and record the results.
5.
With the key in the off position, turn on the vehicles lights manually and using a
volt meter monitor the main battery’s voltage. It should drop steadily as the load
from the light circuit slowly drains power from the main battery. Now monitor the
auxiliary battery voltage. It should stay constant at the previously recorded
voltage and should not drop while the lights are on.
6.
With the key still in the off position, activate the override switch inside the vehicle.
At this time the indicator led on the switch should be on. Turn on the vehicles
lights again and check the auxiliary battery’s voltage. It should now be falling at
the same rate as the main battery. If the system does not behave as expected
please contact us for additional assistance.
