Hi Everyone..

First time poster.

I just installed a new alternator and battery in my '04 Expedition 5.4L. Alt went belly up all of sudden yesterday afternoon. Battery was original so I replaced that also. The problem is the battery light is still on although the guage (which is rather useless) reads jsut above 1/2 way. I get 14.3v at the battery with a voltmeter while running so everything seems good on the charging side. I actually ran a couple hours worth of "poor mans" load tests last night with lights ac blowers etc and the voltage stayed at 14 or above during all of it. With all that stuff off it charges back up.. The light just won't go out.

I am told that I had a stock 110A alternator (the determining questions for all the parts stores seemed to be whether or not I had a factory Nav system, which I do not 110=no Nav, 130=Nav) What I have now may very well be a 130A, although the parts store kept making contradicting statements about the color of the regulater being black or white. They told me they only had a 110A in stock, and considering that's what I should ahve I bought it. When I got home I saw on the back a plastic tab says 130A. I was told upgrading to 130A was not a problem so I went with it.

Either I have a 100A which is what I was supposed to have in there or I have an upgrade to a 130A.

Could this cause the light to stay on or do I have another problem?
