Battery light on, battery draining?

Hi,

Are you getting power at the black wire with the orange tracer at the alternator? If not, there could be an issue with the starter relay.

Take a look at the pics below. They are the schematics for the charging circuit. Check the aforementioned wire for power.

Next, the idea that the battery drains in 15 minutes is concerning. That sounds like there could be a short at some point.

Check to make sure there isn't an issue at the starter relay and let me know what you find.

Also, if you haven't already, check to see if the alternator is charging when the engine is running. All you need is a voltmeter or multimeter.

Here is a link that shows how to check:

Let me know.

Take care,

Joe
