I replaced the head gaskets on my 91 sweet sixteen this past winter & now I have some woes I believe are all electrical. Check this out:
- Oil pressure gauge reads high. 70 psi at idle after the engine is warmed up.
- Temperature gauge reads low. Around 110 to 115 degrees F
- The hour meter doesn't work at all
- The fuel gauge does not work at all
- The tach either works erattically or doesn't work at all. It will flick and jump about, shooting up for no reason when the motor is at idle, for example.
- The shift interupter also either works erattically or doesn't work at all.
I know I want to deal with the shift interupter first, as it is making it difficult to drive the boat. I believe the Tach and shift interupter problems may be related. The other problems could just be bad gauges, faulty sending units or bad wiring.
Has anybody else had a shift interupter problem like this? I know it's not the overstroke switch, as I've tested it and the wiring appears to be ok. My first inclination is to replace the ESA Module.
Thanks for any help.
