Tackometer problem

[Jack Hutteball]

Started the engine today, first time in about 3 months and noted the tackometer was not working.  That is the first time that has happened (90 hours on engine).  The strange thing is that when I switch on the bilge blower the tack works, and stops again when the blower is turned off. Any suggestions?  Also, every time I run the engine all the gauges fog up right after starting and then clear up in 20 to 30 minutes.  Is this normal?

The tach not working is most likely a bad ground.  Had the same thing happen on our '87 C27.  Check all the ground connections on the instrument panel and all connections at the alternator.  Be sure they are clean and tight.

No clue about the instruments fogging up??

Thank you for the information Ron.  If I keep working at it I will get to know our boat like so many of you do!
