FI SYSTEM DIAGNOSIS 4-9 USING THE MULTI-CIRCUIT TESTER • Use the Suzuki multi-circuit tester set (09900-25008). • Use well-charged batteries in the tester. • Be sure to set the tester to the correct testing range. USING THE TESTER • Incorrectly connecting the + and - probes may cause the inside of the tester to burnout. • If the voltage and current are not known, make measure- ments using the highest range. • When measuring the resistance with the multi-circuit tester 1, ∞ will be shown as 10.00 MΩ and “1” flashes in the display. • Check that no voltage is applied before making the measure- ment. If voltage is applied the tester may be damaged. • After using the tester, turn the power off. 09900-25008: Multi-circuit tester set E NOTE: L * When connecting the multi-circuit tester, use the needle pointed probe to the back side of the lead wire coupler and P connect the probes of tester to them. * Use the needle pointed probe to prevent the rubber of the M water proof coupler from damage.
