ELEC Electrical system– +8-23 67C3K117. Check the oil pressure switch for continu-ity at the specified pressures. Replace ifout of specification.NOTE:Slowly operate the special service tool.NOTE:Apply pressure to the oil pressure switchgradually. The oil pressure switch is operat-ing correctly if the digital tester indicationchanges from continuity to no continuity inthe range of 15.5 ± 5.2 kPa (0.155 ± 0.052kgf/cm 2, 2.248 ± 0.754 psi).8. Install the oil pressure switch, and thenconnect the oil pressure switch connec-tor.Checking the warning indicatorassembly1. Disconnect the thermo sensor coupler,and then ground the brown/black (Br/B)terminal (wiring harness end).2. Start the engine, and then check that theoverheat warning indicator comes onafter about 60 seconds.3. Push the engine stop button. (M model)Turn the engine start switch to “OFF.” (Eand W model)4. Disconnect the oil pressure switch con-nector, and then ground the pink (P) lead(wiring harness end).5. Start the engine, and then check that theoil pressure warning indicator comes onafter about 10 seconds.6. Push the engine stop button. (M model)Turn the engine start switch to “OFF.” (Eand W model)7. Connect the thermo sensor coupler andoil pressure switch connector.8. Disconnect the warning indicator assem-bly coupler.9. Connect the yellow/black (Y/B) lead (Mmodel) or yellow (Y) lead (E and Wmodel) to the positive penlight batteryterminal (1.5 V) and connect thepink/black (P/B) lead to the negative ter-minal, and then check that the overheatwarning indicator comes on. Replace thewarning indicator assembly if it does notcome on.Oil pressure switch continuity:Oil pressure switch – GroundPressure ContinuityMore than 15.5 kPa(0.155 kgf/cm2 , 2.248 psi) NoLess than 15.5 kPa(0.155 kgf/cm2 , 2.248 psi) YesS6AG8130S67C8076+-P/BY/BÈ
