If current leakage exceeds the standard value, a shortedcircuit is likely to exist.After warming up the engine, replace the battery with afully charged battery.Connect a tester between the battery terminals.Connect an ampere meter between the terminals of themain fuse.Turn the headlight ON and start the engine.Gradually increase the engine speed and measure thecharging voltage at the specified rpm.CONTROL VOLTAGE : 14.5±1.0V / 5,000rpmTOOL : DIGITAL TESTER, AMPERE METER, SCANNERCHARGING VOLTAGE INSPECTION17-4BATTERY/CHARGING SYSTEMAMPERE METERBATTERY TERMINALGROUND CABLEDIGITAL TESTERAMPERE METERMAINFUSETERMINALSMAIN FUSE•When measuring current using a tester, set it to a highrange, and then bring the range down to anappropriate level. Current flow higher than the rangeselected may blow out the fuse in the tester.•While measuring current, do not turn the ignition on.A sudden surge of current may blow out the fuse inthe tester.•Be sure that the battery is fully charged beforeperforming this test. The amount of current flow maychange abruptly if not sufficiently charged. Use abattery whose specific gravity is 13.0 ~ 13.2V.•When the engine is started using the starter motor, alarge amount of current may flow from the batterytemporarily.•If the probes are connected in reverse order, theregistered current flow direction when charging anddischarging the battery will be reversed as well.•Do not disconnect the battery or any cable in thecharging system without first switching off theignition switch.•Failure to follow this precaution can damage thetester or electrical components.CHARGING SYSTEM INSPECTIONCURRENT LEAKAGE INSPECITIONTurn the ignition switch off and disconnect thenegative battery cable from the battery.Connect an ampere meter between negative (-)terminal and ground cable.With the ignition switch off, check for current leakage.LEAK CURRENT : Not to exceed 1mATOOL : DIGITAL TESTER
