Another concern was the lack of an external voltage sense connection.Again, this is something most manufacturers have stopped doing a long time ago.However, unless you’re powering a huge audio system, have air compressors, video monitors, and lots of additional lighting on your show car, you don’t really need to get the biggest and most powerful alternator.We checked out Powermaster Performance and Tuff Stuff Performance to get a better idea of how to choose a one-wire alternator, and to learn more about them.What was happening was that a wire was sent to a remote location on the car and it would send a signal back to the alternator reporting what the end voltage was.

But now that people are driving their classic cars more often, and upgrading them to be more drivable, they are also adding more electrical components so that driving them is more enjoyable.Likewise, high output alternators aren’t going to improve the quality of electrical components because they consume the power they need and nothing more.They will improve their effectiveness when the alternator is installed correctly, but when a 100-amp alternator will suffice, 200 amps will do very little other than empty your wallet more.When one-wire alternators first came out, those were valid concerns: low output at idle meant sitting at a light with headlights and stereo blasting wasn’t good for the electrical system or the battery.Some alternators required revving the engine to a certain RPM in order to excite the alternator so it would turn on and start charging.It’s not so rare anymore to see a classic Chevy with a bass-thumping sound system, or to see lighting systems that put out more than the standard 55/60-watt headlamps.
