My battery light started flickering at night around town.
When get on open road and revs are up light goes off.
Also noticed the battery voltage guage swinging from 8 to normal.
Tested battery and they are good.
Monitor says charging system failure.
So I started looking at new alternators and see some OBS 7.3 have 200 amp alternator.
How do I know which I have or does it matter?
Meaning can I just buy a 200 amper?
I have the 8 rib belt.
March 97 build date.
The right (passenger) positive battery post has 3 big wires coming off it.
Also any suggestions on which brand alternator to buy?
I love my truck and plan keep long time
