The typical connections on a Ford alternator with an internal regulator are:
* Battery (B+): This is the large positive cable directly from the battery.
* Ignition (I): A smaller wire, often thinner gauge, that provides power from the ignition switch. This allows the alternator to begin charging only when the engine is running. Sometimes labeled "S" (sense).
* Output (Terminal): This is where the positive charging current flows *to* the battery through the main charging cable.
Troubleshooting, not hooking up: If you're having charging problems, the problem isn't hooking up the regulator (you can't, it's internal), but rather:
* Alternator failure: The most common cause. A faulty alternator needs to be replaced.
* Loose or corroded connections: Check all the battery terminals and alternator connections for tightness and corrosion. Clean them if needed.
* Faulty battery: A bad battery can prevent proper charging.
* Wiring issues: Check the wiring between the battery, ignition switch and alternator for breaks or shorts.
* Ignition switch problem: A faulty ignition switch might not provide the necessary power to the alternator.
In short: There is no separate "hooking up" of a Ford internal voltage regulator. Address charging issues by focusing on the alternator, battery, and related wiring. If you're still experiencing problems, you'll likely need a mechanic or auto electrician to diagnose the specific fault.
