Electrical question: I run an electric tach off the alternator of my T6.354 Perkins. Since purchase the tach works about half the time, showing accurate RPM and then a few minutes later back to zero. I've run a new ground but no change. The question I have is this: Can I check for the alternator pulse at the tach, using a volt meter or continuity tester to see if the tach is getting a constant signal? This tach is new as I replaced the original when it had the same problem.
