Charging system problems

Welcome to 2CarPros.

There are a few things that should be checked. First, check the fuses identified in picture 1. They are located in the under hood fuse box.

If the fuses are good, you need to check what is called a fusible link. It will appear to be a regular wire, but it functions as a fuse and can burn out. It is what allows power between the battery and the alternator. Take a look at picture 2. You need to locate the black/white wire that runs from the B+ pin on the alternator and battery cable junction block and check it for continuity. When doing this, disconnect the battery so no power is available to the wire.

You will need to use a multi meter to check continuity. Here are a couple links that you may find helpful:

I have a feeling the fusible link has failed, but you need to check it for continuity to confirm it's bad.

Let me know if this helps or if you have other questions.

Take care,

Move the fusible link around to see if it makes a difference. You may have a poor connection or an internally broken wire allowing power and then not. If you had power, that is my first suspect. Also, confirm the connections are not corroded or loose.
