As I said in my previous post, you can hook the voltage sense wire to the
Batt. Terminal on the alternator but it's better if you hook it somewhere
else in the system to measure the voltage actually delivered to the
components not what is at the Batt terminal. There can be considerable
voltage loss in the wiring and connectors at high amperage, enough to make
the difference between a fully charged battery and a partially charged
battery. The regulator will think it's putting out enough voltage if the
sense wire is hooked to the batt terminal on the alternator but what is
getting to the battery is less.
Your local wrecker is taking the easy way out but not the best.
