Troubleshooting Tests
Testing for Voltage
When testing for voltage at a connector
without wire seals, you do not have to
seoarate the two halves of the connector.
lnstead. orobe the connector from the back
Always check both sides of the connector
because dirty, corroded, and bent terminals
can cause problems (no electrical contact =
an open).
1. Connect one lead of the test light to a
known good ground, or, if you're using a
digital volt ohmmeter (DVOM), place it in
the appropriate DC volts range, and
connect its negative lead to ground.
Connect the other lead of the test light or
DVOM to the point you want to checK.
lf the test light glows, there is voltage
presenl. lf you're using a DVOM, note the
voltage reading. lt should be within one
volt of measured battery voltage.
A loss of more than one volt indicates
a oroblem.
NOTE: Always use a DVOM on high
impedance circuits. A test light may not
glow (even with battery voltage present).

Testing for Continuity
When testing for continuity at a connector
without wire seals, you do not have to
separate the two halves of lhe connector'
lnstead. orobe the connector from the back.
Always check both sides of the connectol
because dirty. corroded. and bent terminals
can cause problems (no electrical contact =
an open).
1. Disconnect the negative cable from the car
battery. lf you're using a DVOM, place it in
the lowest "OHMS" range.
2. Connect one lead of a self-powered test
light or DVOM to one end of the part of the
circuit vou want to test.
Connect the other lead to the other end.
lf the seltpowered test light glows, there is
continuity. l{ you're using a DVOM, a low
reading or no reading (zero), means
good continuity.

How To Use This Manual
Troubleshooting Tests
Testing for Voltage Drop
Wires, connectors, and switches are designed
to conduct current with a minimum loss of
voltage. A voltage drop of more than one volt
indicates a oroblem.
1. Place the digital volvohmmeter (DVOM) in
the appropriate DC volts range. Connect
the positive lead to the end of the wire
(or to the connector or switch) closest to
the battery.
Connect the negative lead to the other
end of the wire (or the other side of the
connector or switch).
Turn on the components in the circuit.
The DVOM will show the difference
in voltage between the two points. A
difference, or drop, of more than one
volt indicates a oroblem. Check the
circuit for loose, dirty, or bent terminals.

Light or DVOM
1. Remove the blown fuse and disconnect
the load.
2. Connect a test light or digital volvohmmeter
(DVOM), switched to the appropriate DC
volts range, across the fuse terminals to
make sure voltage is present. You might
have to turn the ignition switch to ON;
check the schematic to see.

Beginning near the f use box, wiggle the
harness. Continue this at convenient ooints
about six inches apart while watching the
test light or DVOM.
Where the test light goes off, or the DVOM
voltage drops to zero, there is a short to
ground in the wiring near that point.
NOTE: Always use a DVOM on high
impedance crrcuits. A test light may not
glow (even with battery voltage present).
