This past weekend when I was heading back to the ramp my tachometer quit on me. It worked fine all day. Just before it failed i was at about 3/4 throttle when i noticed the gauge started to bounce. It went from 2000 to 5000 back and forth a few times and then finally died. Any ideas? Another possible symptom that could be related is a few weeks ago all of the gauges quit working a few times. After restarting the boat a few times it went away and all have worked ever since. Could the tach be related to the Medallion MDC-1600?
