My tachometer does not seem to effect the running of the engine and seem to be working (mostly). Prior to my engine swap it did not see anything aver 5500 rpm. It does bounce a bit but stabilizes after a few seconds.
Now when I rev the engine past 5800, the tack drops to zero and starts bouncing(not in control). If you were not looking at the tach you would not know anything was going on. SO it is not the rev limiter cap rotor wires or such
I am driving the tach with the Hifire VI AL yellow tach signal wire. Feels like the tach is getting ready to fail or the old capacitors in the unit are old and shot?
Any one have any experience with a failing tachometer?
