Someone please help me out. Here's the deal. My alternator has not been charging my battery and I couldn't figure out why, so I started tracing cables. Here's what I found.
It APPEARS the positive battery cable is grounded to the car (intentionally or unintentionally). The positive battery cable has TWO cables. The first, of course, is the big thick red cable. The second, is a black cable with a red stripe. It appears to be grounded to the car. ALSO, there is another smaller black cable with a red stripe that is terminated and it runs back toward the car. Not sure what it is. Where it is grounded, it appears that there are other cables that are for power, but what they're supplying, I have no idea, but two of the cables (orange and red) appear to go to a plug on the passenger fender.
