Grand AM V6-3100 3.1L MFI VIN M (1994)
3. Replace the fuse.
^
If the fuse blows, the short is in the wiring leading to the first connector or switch. Use a test light or meter as described in Test Light/Digital
Voltmeter.
^
If fuse does not blow, refer to next step.
4. Close each connector or switch until the fuse blows in order to find which circuit has the short. Connect test lamp or meter at the connector to the
suspect circuit (disconnected) rather than at the fuse terminals.
Testing For Voltage
Voltage Check
1. Connect one lead of a test light to a known good ground. When using a Digital Voltmeter (DVM), be sure the voltmeter's negative lead is
connected to ground.
2. Connect the other lead of the test light or voltmeter to a selected test point (connector or terminal).
3. If the test light illuminates, there is voltage present. When using a DVM, note the voltage reading.
Testing For Continuity
Continuity Check Through A Switch
1. Remove the fuse to the circuit involved.
2. Connect one lead of a self-powered test light or ohmmeter to one end of the part of the circuit you wish to test.
3. Connect the other lead to the other end of the circuit.
4. If the self-powered test light glows, there is continuity. When using an ohmmeter, low or no resistance means good continuity.
Testing For Voltage Drop
