Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-megaohm or
higher impedance digital multimeter.
Never use a test light or analog meter on circuit that contain solid-state devices. Damage to the devices
may result.
Test light and DVOM
On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12-volt
bulb with a pair of leads attached.
After grounding one lead, touch the other lead to various points along the circuit where voltage should be
present. The bulb will go on if there is voltage at the point being tested.
If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM).
Self-powered test light and DVOM
1. Use a self- powered test light to check for continuity.
This tool is made up of a light bulb, battery, and two leads. To test it, touch the leads together, the light
should go on.
Use a self-powered test light only on an unpowered circuit. First, disconnect the battery, or remove the fuse
that feeds the circuit between which you want to check continuity.
Connect one lead of the self-powered test light to each point. If there is continuity, the test light's circuit will
be completed, and the light will go on.
Fused jumper wire
Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a
set of test leads. It should have a five ampere fuse.
Never use a jumper wire across any load. This direct battery short will blow the fuse.
Short finder
1. Short finder are available to locate shorts to ground. The short finder creates a pulsing magnetic field in the
shorted circuit and shows you the location of the short through interior trim. Its use is explained in the
following troubleshooting tests.
Testing for voltage
This test measures voltage in a circuit. When testing for voltage at a connector, you may not have to separate
the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the
connector because dirt and corrosion between its contact surfaces can cause electrical problems.
