F250 Tacho Problems
I've got an F250 with a 7.3L NA Diesel and I'm having "issues" with the tacho. When its pretty cold, it hardly works, when it warms up a little, its fine and when it gets normalor hot, the tacho only works about approx 1800 RPM. Has anyone seen this before? Does anyone know how the tacho gets its signal? Any clues for desparate Ford Truck owner?
