[Shotimes] Electrical/Alternator Question...Ford, but not SHO

[Paul Nimz]

The two big wires more than likely go to the same place and have fuse links
in them.  The small wire is another story.

>From what I have read the battery light will come on if there is an fault in
either direction.  The best I can do is send you here so you can digest the
info.  http://www.vtr.org/maintain/alternator-overview.html
