ELECTRICAL Multimeter Usage
= Ohms, resistancemeasuring component resistance valuestesting coils, wiring, etcUsed to test resistance to the flow of electricity in circuit or componentA reading of OL means an open circuit or infinite resistanceSometimes the leads themselves will have some resistanceTouch the leads together and subtract this resistance from the component reading to achieve the actual readingTest Method 1234Connect black lead to Com () meter terminal Connect red lead to (+) meter terminalTurn selector dial to settingIsolate test component from the rest of the electrical circuit by disconnecting wires from harness5Connect test leads to the circuit to be testedUsage Testing coil resistance Testing switch operation Testing wire continuity_
