HOW DO I TEST THE BATTERY PACK?
The best way to test a battery is to test it with a load. This test can be performed a couple of different ways.
Using a voltage meter, attach the leads of the meter to the charging plug of the motor. Using the motor as the load, drive
the kart and watch the meter. If the battery pack is ok, you will see the battery voltage drop slowly as the motor draws
power. If you see the voltage drop suddenly, then you must go to the next test to determine where the problem is.
The second test can be done in place of the first test, but it requires more work. Individually test each battery with a load
tester; follow the instructions on the tester. If you completed the first test and found a problem, this test should show you
which battery in the series has an issue.
WHAT DO I DO IF A BATTERY FAILED THE LOAD TEST?
All of the batteries should be removed and put on a maintenance charger to charge them individually. In many cases, the
battery that was showing the issue can be fixed by charging it outside the pack. The other batteries in the pack should be
charged separately as well. We recommend keeping 4 replacement batteries as back-up for this very purpose.
HOW DO YOU TEST THE FUSE TO KNOW IF IT IS GOOD?
In many cases, when the fuse fails it is possible to visually see the failure. However, sometimes a fuse will look good and
still be bad. You should use a voltage meter in the Ohm setting to check the continuity of the fuse.
WHAT CAUSES A FUSE TO FAIL?
A fuse is a device designed to fail if the amp draw exceeds a predetermined amount. It prevents catastrophic damage to
the electrical equipment. When a fuse fails, it is a good idea to inspect the electrical equipment for damage and a possible
cause for the failure.
WHAT WOULD HAPPEN IF THE KART IS TURNED ON AND RELAY DOES NOT WORK?
When the on/off switch is turned on, a signal is sent to the relay to allow power to go from the relay to the controller. If
the power is not sent to the controller from the relay, there would be no light on the controller and the kart would not
function at all.
HOW DO I TEST THE RELAY?
See page 13-17.
HOW DO I TEST THE INTERCONNECT BOARD?
As it would be difficult to individually test each connection and trace on the board, the easiest way to test an interconnect
board would be to put the questionable board into a kart that is known to work properly.
CAN THE INTERCONNECT BOARD BE FIXED?
The interconnect board should not be repaired.
HOW CAN I TEST THE SWITCH BOX?
The best way to rule out a problem with the switch box is to try a switch box that is known to work properly in place of
the questionable unit (you do not have to remove the existing switch box to perform this test).
