MEASURING CONTINUITY/RESISTANCE

Switches
Touch the ohmmeter leads to the switch terminals to
check for continuity.
Diodes
Connect the ohmmeter leads as shown in the figure to
check for continuity. If the leads are reversed, continuity
will not be indicated by the ohmmeter.

Note
* The negative (-) lead of the ohmmeter is connected
to the positive terminal of the internal ohmmeter bat­
tery; the positive (+) lead to the negative terminal of
the battery.
Sensors and Solenoid Valves
Touch the ohmmeter leads to the terminals of the sen­
sor or solenoid valve to check the resistance.
Capacitors
1. Short between the terminals with a jumper wire to dis­
charge the capacitor.
2. Set the ohmmeter range to x10 kQ and connect the
ohmmeter leads to the capacitor terminals.
3. The capacitor is good if the needle of the ohmmeter
swings once and returns to its original position.
