Hello all, new member here looking for advice and help.
I have a mag pickup into a common emitter amplifier with that output going into a switching transistor. The load being a coil that on collapsing is intended to replicate an ignition coil to drive the tach. Amplifier works great giving a nice output when tested by itself. Tach adapter works as it should when it is used by itself and fed a 3 volt ppk sine wave or square wave. BUT tie them together, the tach initially reads then fizzles to zero.
Any ideas out there? Really want this to work
Cheers
