Bouncing rev counter

Not electrically shielded enough? HT interference generation is greater when accelerating. Bigger spark needed. Check the rev counter wire is shielded and the shielding is earthed at only one end of the wire. Check you are using suppressed HT leads. Check the shell of the rev counter is earthed.

When mine was bouncing it turned out to be a knackered coil. That might also be worth looking especially as mine didn't have the right one on it to begin with

Hi Dean

Its a brand new coil as old one was all corroded inside, I got a compatible (used old unipart code from old unit).

Ive seen that putting a 10k resistor on the -ve signal lead can help so going with that first
