5. TEST EQUIPMENT AND SOME APPLICATIONS

Special Equipment Required:
To Make Test Lamp or Jumper Lead — Soldering
iron

When working on the electrical system, a test
lamp and jumper leads can be very useful to check
circuits.

TO MAKE A JUMPER LEAD
The minimum materials required to make a
jumper lead are one length of 4 mm wire and two
small alligator clips.

Grouping of materials to construct jumper leads of
various sizes.
Bare both ends of a suitable length of 4 mm
wire. Connect a small alligato r clip to each end of
the wire. Solder and tape the connections. Test the jumper lead for continuity by re-
moving one battery cable and connecting the lead
between the cable and the battery terminal. Turn the
ignition On and the dashboard warning lamps should
operate indicating a completed circuit through the
jumper lead. Remove the jumper lead from the circuit and
reconnect the battery.
NOTE: Make a few jumper leads of various
lengths using different sizes and types of
alligator and battery clips.

TO MAKE A TEST LAMP
Due to the extensive use of electronic components
in the electrical system, an LED (light emitting diode)
test lamp can be made from a suitable length of 3 mm
wire, an alligator clip, an LED, a 1/4 watt 560 ohm
resistor, a suitable case such as an old ball point pen
case and a length of rod or wire sharpened to form a
probe.

(1) Solder the length of wire to the K (cathode)
