View Full Version : Help fine tune 4160 Holley

What voltage should my battery read at idle and what voltage should it read while running above idle. I sometimes get an audible alarm when the boat idles for a few minutes. When the boat is running I only read about 13 volts.

I took the battery to Autozone and had them check it out and they said it was ok. I also took my alternator to a local rebuild shop and again no problem found.

Any suggestions.
