General
The following test equipment comes in a variety of styles and are adequate for simple tests. However, when accuracy becomes important, the value of a
reading obtained using a meter is critical to the diagnosis procedure. Make sure any electrical test meter used is of sufficient quality and accuracy to
make the measurements required in the electrical testing.
Jumper Wires
Jumper wires allow "jumping" across a suspected open or break in a circuit.
-
If the circuit works properly with the jumper wire in place, but does not work when the jumper wire is removed, the circuit has an open spot.
-
A circuit without any opens or breaks has continuity and needs no further testing.
The jumper is usually a long wire with alligator clips. A version of the jumper has a fuse holder in it with a 10-amp fuse. This will prevent damaging the
circuit if the jumper is connected in the wrong way.
The jumper is used to locate opens in a circuit. One end of the jumper is attached to a voltage source and the other end is attached to the load in the
circuit, i.e. lamps or motors. If the load works, try "jumping" to circuit points that are progressively closer to the voltage supply. When the circuit load
stops working, the open has been located.
The jumper is also used to test components in the circuit such as connectors, switches and suspected high resistance points.
Unpowered Test Lamp
This tool consists of a 12-volt lamp with leads. The ends of the leads usually have alligator clips, but various kinds of probes, terminal spades and
special connectors also are used.
The 12-volt test lamp continuity tester uses the vehicle's battery to provide voltage to the circuit being tested. 12-volt testers are manufactured with a
