Tach on mercury 200 efi
I replaced tach a few months ago. It was working fine then one day it just stopped registering rpm. Changed both regulators and it is still not working. Any ideas?
thanks

Id run a dedicated wire from grey wire back at voltage regulator directly to tach might have a bad wire in harness .

Well I checked it with the wire for my temp gauge and it was working so I guess the wire was bad. I will run a new wire.
