Low volts at idle

So you're saying to bypass the ammeter then just run a new wire from the alternator to the relay and leave everything else alone? Because right now I have 2 wires connected to the 1 post on my alternator and then 1 field wire. So if I run a new wire to the relay, do I have to remove either of the 2 that are currently connected to that same post?

Either follow the article exactly, or alternately, add the new wire. Leave the existing wire (s) on the alternator. I believe that one of them feeds your horn relay.
