Charging System/Battery light still on Sign In
Hello,
My 1998 Ford Contour 2.5L with an automatic transmission charging system/battery light is staying on when running. We have just done the following repairs and checks:
New battery
New Alternator
New Serpentine Belt
New Mega Fuse 175 amp
New Maxi Fuse 80 amp
Check all other fuses in both fuse boxes (all appear to be good)
Check grounds (good)
Checked wiring (good)
So my question is what can be causing my charging system/battery light to stay on and I need to do to get it to turn off correctly?

If the charging system isn't operation, the battery light will be on. To get it to go off you need to diagnose it correctly.

What is the charging system voltage at the battery and at the output lug at the alternator with the engine running?


There is also a TSB that may be related to your problem:

ISSUE
The charging system indicator may illuminate or vehicle may not start. This may be caused by a discharged battery due to a poor electrical connection at the generator terminal.

2. Replace the generator B+ terminal with a new Terminal (F3RZ-10329-A8).
