ELECTRICAL SYSTEM 9-5 USING THE MULTI-CIRCUIT TESTER • Properly use the multi-circuit tester + and - probes. Improper use can cause damage to the motorcycle and tester. • If the voltage and current values are not known, begin mea- suring in the highest range. • When measuring the resistance, make sure that no voltage is applied. If voltage is applied, the tester will be damaged. • After using the tester, be sure to turn the switch to the OFF position. 09900-25008: Multi-circuit tester set  Before using the multi-circuit tester, read its instruc- tion manual. NOTE: * When connecting the multi-circuit tester, use the needle pointed probe to the back side of the lead wire coupler and connect the probes of tester to them. * Use the needle pointed probe to prevent the rubber of the E water proof coupler from damage.
