Interesting... was winter prepping my 75 last week, making sure antifreeze was to strength and putting stabilizer in the gas. Was about -10 in the garage, started up to circulate fluids and noted my tach was not working. Warmed car up and heater on, tach started working. Seems to be a temp related thing...
