Greetings I have a 1989 SR 300 Weekender with twin 5.7s. Port engine has a water gauge and RPM gauge issue i am hoping someone will help with.
Water Temp - gauge is dead on zero. i checked the gauge for loose connections / grounds. anyone have a photo or exact description where on the engine is the actual sending unit so I can clean / heck grounds there?
RPM - gauge intermittently jumps around. the engine is not actually surging - just a gauge issue. again, Ive checked the gauge end for loose / good connections. can anyone help with photo / description where on the engine the wire actually connects for the rpm signal?
thanks
