Re: Cooling problem solved now what's wrong with my tach?
If you have a "one wire" alternator, where the sense lead is tied back to the output (usually at the starter lead) then you may also have to blip the engine to get the alternator to turn on, and the tach won't read until then. Blip can mean 2x-3x cruising speed for 5-10 seconds.
