It shows 14.2V mostly.  But while listening to or even sometimes not listening to my music it’ll jump around from 12.3 to 14.2V. It did alarm out the charging system a while back and that led me to disconnect the audio system from the batteries.  I also went and had the alternator tested. It was a 250A and Honda said it was bad. I bought a new alternator and have installed it. So far, the charging system hasn’t alarmed out, but the voltage is moving like it was before.  So I need a ground wire from the alternator to the chassis as well as a wire from the negative battery terminal to the chassis?</blockquote>
