Battery light on after engine swap (not the alt)
So I swapped from a 4.3L V6 to a 5.3L V8 on my 2003 Silverado 1500. I have the following codes on:
p0315 - crank relearn
p0178 - fuel composition sensor (my truck isnt e85 but the computer must think it is)
p0480/481 - efans
my battery light is on but im getting 14 volts. I checked all the wiring and I have 1 ohm from the batt to the alt, batt to frame, frame to motor, and motor to batt. I did the big 3 upgrade and also tried a new 105 amp alternator with no success. it left me thinking that the truck was calling for a 145 amp alternator, so i went out and got one. still no success.
any suggestions? for some reason i dont think its tuning related
