I'm in the process of replacing the old AQ110 petrol engine (negative
earth)
in my boat with a Perkins Diesel.
Is it possible to retain my original Rev Counter (signal from contact
breaker), but pickup the signal from the Alternator instead and
recalibrate
the instrument (I have an accurate hand held tacho to compare it with)?

Regards,
Brian
