'68 Barracuda - charging system questions

thanks - I got most of that. we'll check reading at correct terminal on VR with it running later today. Another question came up your expertise can address: If I do ammeter bypass wire (alt to starter relay) and just leave the rest of wiring in place that routes through the ammeter, will this reduce load that goes through the ammeter and help reduce chances of frying? I know others doing this disconnect the ammeter and join it's wires together and some don't.
