Good day Comrades,

I´ll get the "Battery not charging" light and I did some testing but with no result so far. The engine is off and the battery shows 12.6 Volts, when running in idle or with high refs I´ll get only 13 Volts on the multimeter but not higher than that.
I have changed the ground wire from the battery, with the 2 wire connector which will cut the battery if an accident happens, but it´s still the same. Any other thoughts what I should do next ? Checking fuses ? I did some but not all I guess.


Thanks
Frank

 

Get a new alternator. Yours is shot.

 

The 5.0L workshop manual has some specific testing for this problem. See the X150 stickies where you can download the manual.
