recently every 20 times my car will need a jump. my dad thought it was the battery but we replaced it but still the same problem.
so we spent 400$ on a new alternator but we found out that the old alternator wasnt to far from the new one?

something about the voltage being on the old one at like 13.5 and new ones are at 14.5? idk i didnt really understand

if its not a bad alternator what else could it be?

possibly a blown fuse?

 

u should check see if theres things in ur car that might drain the battery??? sometime its simple stuff as in a small light thats left on or something...
