Tach Problems
I recently replaced the tach circuit board in my '75, as the tachometer wasn't working at all. Since I replaced the board it works, although when it hits 4500 rpm it seems to die; it falls back to around 3000, and continues to climb from there. I bypassed the filter with no effect and am at a loss as to what the problem may be.
