Testing for a Short with a Sell-Powered
Test Light or DVOM
1. Remove the blown fuse and disconnect
the battery and load.
2. Connect one lead of a self-powered test
light or digital volUohmmeter (DVOM)
(switched to the lowest "OHMS" range) to
the fuse terminal on the load side.
Dlsconnect the batlery.
FUSEBOXRemove the fuse.

Connect the other lead to a known
good ground.
Beginning near the fuse box, wiggle the
harness. Continue this at convenient
points about six inches apart while
watching the test light or DVOM.
lf the self-powered test light goes on or
the DVOM displays a low reading or no
reading (zero), there is a short to ground
in the wiring near that Point.

Testing tor a Short with a Short Circuit
Locator (Short Finder)
1 . Remove the blown fuse. Leave the
battery connected.
2. Connect the short finder across the battery
terminals and the load (component) side of
the fuse terminal.

How To Use This Manual
Troubleshooting Tests (cont'd)
4. Turn on the short finder. This creates a
pulsing magnetic field around the wiring
between the fuse box and the short.
5. Beginning at the fuse box, slowly move
the short finder along the circuit wiring.
The meter will show current Dulses
through sheet metal and body trim. As
long as the meter is between the fuse and
lhe short, the needle will move with each
current pulse. Once you move the meter
past the point of the short, the needle will
stop moving. Check the wiring and
connectors in this area to locate the cause
of the short.
