II-GM6 Troubleshooting
Finding short circuits
Shorts occur between the power(positive) and ground(negative) sides of a circuit.
Therefore, finding a shdit circuit requires determining how the circuit is routed.
Circuits not connected to control unit
Examples
Indication
0 Fuse melts. Finding short circuit
0
Test lamp 1. Remove the fuse and
main fuse of the circurt.
2. Disconnect all connectors
of electrical components
in the circuit.
3. Attach a voltmeter or test
lamp to the fuse box and
reconnect each
connector, beginning
nearest the power
source.
4. Check the voltmeter or
see if the test lamp lights
as the connectors are
connected. Finding short circuit
,,{:““o
1. Remove the fuse and main
fuse of the circuit.
2. Disconnect all connectors of
/ electrical components in the
circuit.
Test lamp 3. Attach a voltmeter or test
lamp to the fuse box and
reconnect each connector,
beginning nearest the power
4. Check the voltmeter or see
if the test lamp lights as the
connectors are connected.
Sensor/switch
1. Attach the test lamp or
voltmeter to the CPU
connector.
2. Connect to the swrtch/
sensor connector.
3. Check the voltmeter or see
if the test lamp lights.
A short has occurred where voltmeter
reads OV or the test lamp goes out,
