[Healeys] Tach way off

[RACarbone]

Bob,

If I understand correctly, you problem is relatively common and the readings
will get even divergently higher over time.  It is a failing capacitor and can
be easily replaced and the tachometer celebrated.  A while back, Frank
Filangeri wrote a paper, bBJ8 Tachometer Reads Highb, on the fix that can
be found on www.healey6.com (John Sims web site).  I did the fix about 15
years ago and have had no additional problems.
