78 SA Tach problems
My tach works great part of the time. Then it sometimes freezes at high RPM, and sometimes doen't move at all. Does this sound like a sticky tach or maybe an electrical problem. Thanks Bob.

My Red one (77) Did this for years. some days it would work good all day. mostly it would stick at 3,000 RPM. I finally pulled the tach out about 2 or 3 years ago and put in one of those tach circuit boards all the vendors sell. VERY easy to install once tach is out of car. Been working great.
