5-3 SHORT CIRCUIT TEST

Disassembly:
Disconnect battery negative terminal
cable.
Measure method:
A. Connect megga meter "+"
terminal to battery "-" terminal.
B. Connect megga meter "-"
terminal to circuit negative
bl
Note: User megga meter "A" current
position.
Turn main switch to "OFF"
position.
Inspection: Check if there is electrical
current. If no current, check the main
switch and wire harness for short circuit.
5-4 RECTIFIER
Watch:
(1) Check if wire harness is normal
before checking rectifier and end
resistor. Check if rectifier socket is
well connected.
(2) Keep fingers away from tester probe.
The circuit resistance can be
changed with human body resistance
involved.
