3. If the test lamp glows, there is voltage present. If you are using a voltmeter, note the voltage reading. A loss of more than 1 volt from
specifications indicates a problem.
Troubleshooting Equipment
Short finder is available to locate a short to ground. The short finder creates a pulsing magnetic field in the shorted circuit and shows you the location of
the short through body trim or sheet metal.
Voltmeter and Test Lamp
Use a test lamp or a voltmeter on circuits without solid-state units and use a test lamp to check for voltage. A test lamp is made up of 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. When the bulb
goes on, there is voltage at the point being tested.
CAUTION
A number of circuits include solid-state modules such as Engine Control Module (ECM) used with computer command control injection. Voltage in
these circuits should be tested only with a 10-Mega Ohm or higher impedance digital voltmeter. Never use a test lamp on circuits that contain solid-state
modules. Damage to the modules may result.
A voltmeter can be used in place of a test lamp. While a test lamp shows whether the voltage is present or not, a voltmeter indicates how much voltage is
present.
