Tachometer Problems - No RPM and Hours stuck

kwas911kwas911 Posts: 1 New Baller
I have a 2003 196 SE. The tachometer suddenly stopped working and the digital hours readout at the bottom of the tachometer gauge is stuck at 818. All the other gauges work (analog speedometer is a bit off, but functional). The cables appear to be connected. At the same time the tachometer quite working, the RPM readout on the PerfectPass quit. Not sure what else to check??

    Just had the same issue check the wire that runs from the tach to Perfect pass mine was corroded up in the dash behind the tach. I cleaned it and it works fine. Good luck
