* The main battery cable's fusible link: This is a large fuse (often looks like a short, thick wire) located near the positive (+) battery terminal. This protects the entire charging system. This is the most likely culprit if there's a major charging system problem.
* The alternator itself: Have the alternator tested at an auto parts store. This is far more likely to be the problem than a missing fusible link.
* The wiring between the alternator and battery: Check for any broken or corroded wires in this circuit.
* The voltage regulator (if separate): Some Wagoneers had a separate voltage regulator, while others had it integrated into the alternator. If separate, check its connection and condition.
In short, don't waste time looking for a dedicated alternator fusible link – it's not there. Focus on the components listed above.
