C TROUBLESHOOTING VOLTAGE CHECK (a) Establish conditions in which voltage is check point. Example: A − Ignition SW on B − Ignition SW and SW 1 on C − Ignition SW, SW 1 and Relay on (SW2 off) (b) Using a voltmeter, connect the negative lead to a ground point or negative battery terminal, and a positive lead to the connector or component term This check can be done with a test light instead of a voltmeter. CONTINUITY AND RESISTANCE CHECK (a) Disconnect the battery terminal or wire so there is no voltage between the check points. (b) Contact the two leads of an ohmmeter to each of the check point. If the circuit has diodes, reverse the two leads and check again.
When contacting the negative lead to the diode positive side and the positive lead to the negative side, there should be continuity. When contacting the two leads in reverse, there should be no continuity. (c) Use the volt/ohmmeter with high impedance (10k Ω /V minimum) for troubleshooting of the electrical circuit. 10
