Mr Jerry.....my tach started acting up recently. When the engine is shut off sometimes the tach still shows like 500 rpm. Start the engine and it stays the same, slap the dash near the gauge and it will jump up to a higher rpm. Once underway it seems to work ok. It doesn't do this all the time but I am begging to wonder how accurate it is now. Part # for the tach is F5H012 and several are available on Ebay if I need to replace it. Have not done anything with it yet....wanted to get advice on what to look for first......maybe corrosion, bad connection, wiring, etc. Not sure where the tach gets it's info from so maybe a problem with that?? Thanks.
