Current leakage test
Inspection
Turn off the main switch.
Disconnect the negative terminal wire from the
battery.
Connect ammeter between battery negative
terminal and negative terminal wire (as shown
at left picture).
Caution
In the current leakage test, set the current
range at the largest scale, then gradually
decrease to the lower scale as the test
process goes to avoid possible damage to
the ammeter and the fuse.
Do not turn on the main switch when
testing the current leakage.
If the current leakage is over the standard
value, it shows that short circuit happens.
Current leakage：below 1mA
If the leaked current exceeds the specified
value, it may indicate a short circuit.
