1. Remove the YEL/RED wile from the engine oil pres-
sure switch.
ENGI'{E OIL PRESSURE SWITCH
Check tor continuitv between the positive torminal
and the engine {gtound) with the ignhion swhch OFF.
a lf there is continuity, go to step 3.
a lf there is no continuity, replace the switch.
Check for continuity again, this time with th€ engine
runnrng.
a lf there is continuity, go to step 4,
a lf there is no continuity, the switch is OK.
Make sure engine oil level is OK, then check engin€
oil pressure (s€e section 8).
a lf engine oil pressure is OK, replace the switch'
a lf engine oil pressure is low, check the sngine oil
pump (see section 8) and, if necessary, replac€ it.
