It depends on which system you have. In both cases, there is a black and yellow wire that goes to the fuse box and a 15 amp fuse. This wire provides stator current to run the alternator. There is also a yellow and white wire that goes to the fuse box that provides the charge current to the battery. Now depending on the system, there may be only one additional wire (light green/red) to the instrument panel battery light or there are 2 wires (brown/white and grey/orange) that go to the PCM. In the latter case, the PCM monitors the charge current and then turns on the instrument panel light when the charge current is insufficient. In the former case, the alternator has circuitry to determine when the batter light should turn on. OK? Is there a problem we can help you with?

Having trouble figuring out if i have an external or internal regulator on my 1988 f250 with a 460

Internally regulated Ford alternator will have a three wire plug and a single wire plug next to it. Plus the battery stud. The regulator is normally black or gray in color mounted on the back of alternator. The three wires plugs to the regulator. Externally regulated will not have these plugs. Hope this is helpful.

Own a 2005 Escape, have replaced the alternator three times and replaced the battery 4 times. They are now recommending replacing the computer. Any others with this problem?

If the alternator is what is going out,look at the alternator wiring,the large wire goes to the battery,it is hot all the time,do not remove it,just add a wire as large,or larger to it,and runit to the positive battery post,this will keep the alternator from working so hard to charge.

Battery won't hold charge

My 2002 Ford2.gif Escape had a similar issue later in 2006. My alternator died and I needed replacement. After replacing, the light would come on and off at times. When everything running (i.e. radio2.gif, air conditioner, driving lights) and tocuh electric windows up the power would lower and sometimes battery light on dashboard would come up. Original mechanic could find out what was going on and I lived for 2-3 years with it.

This past August 2009 after a long trip (i.e. 8 hours or so) my battery died. Brought to a auto parts place and they determined it was the baterry and the alternator. Since I was back on my home town I went to a good friend that is a mechanic and he fixed it for real.

He had a similar issue with three different Escapes coming back with alternator or baterry or both death. He found out that Ford has an official report for Escapes that when this happens the electric fan behind the radiator are short circuiting, affect direclty the baterry and alternator killing them, and needs replacement.

Try this and may work for you.
