Charging system light will not turn off?

Hi,

First, I attached the wiring schematic below specific to the charging system so that you have a reference. (see pics 1 and 2)

As far as the battery sensor is concerned, before you replace it, we need to make sure it is bad. Starting with pic 3 below, follow the test directions to confirm that is the issue. Note that the diagnostics indicates possible causes related to the condition found.

Last, if you look at the schematic, you'll notice at the alternator there is a black wire that provides battery voltage. Confirm that is present.

Let me know what you find. Also, let me know if the alternator is charging even though the light is on. If you haven't checked, here is a link that explains how to do it:

Let me know.

Take care,

Hi,

There is a 120-amp main fuse in there that distributes power. Take a look at the pics below. Check to see if there is power to the main fuse. Power is direct from the battery to that fuse. If that fuse fails, you will lose multiple circuits.

Let me know.
