Alternator choice

[Fbks_Cruiser]

I put the buss bar very close to where the old voltage regulator was. Seems to work okay. I can definitely see the ammeter gage move, but just a little right after starting. (Needle never moves much if the charging system is working properly. ) My truck starts easily so the battery doesn’t get drained from excessive cranking. The alternator being a 12SI does a better job of charging at low speed so I don’t see the gage bump up when coming off idle. Before upgrading the alternator and installing headlight relays I had trouble with voltage dropping too low at idle if I had lights, wipers and heater/blower going at the same time. I could see a discharge on the ammeter at idle. Now, with the upgrades, I can have all lights (including 4 high beams since it a GMC), wipers, blower on high etc and ammeter stays rock solid. Voltmeter holds steady too.
