Guidelines on Using a Voltmeter to
Locate Power and Ground
1. First set your voltmeter to the continuity
setting (should beep when you touch the red
and black probes together, telling you they are
shorted).
2. Find a ground on the car somewhere, like a
bolt under the dash, or a metal cross member.
3. Put the black probe on that ground, and
touch the back of each exposed wire connector
in the mirror harness with the red probe.
4. For each wire that beeps, that means that
wire is grounded. Tum the ignition to the on
position, then back to off, and make sure it
beeps regardless of the ignition position.
5. Put the voltmeter into voe mode, to
measure DC volts, turn the ignition to the on
position.
6. Put the black probe on the ground wire
found in #4.
7. Touch each of the wires in that ha mess with
the red probe, and note which one(s) gives you
+12-14 volts, turn the ignition off to verify that
the volt readings go down to zero or close to
zero.
Clear the "clutter" from
your dash by wiring your
radar detector straight into
your fuse box.
