My car began to not start almost every other time i tried to start without being jumped and now will not start at all without being jumped. the battery won’t stay charged and I bought the battery brand new 6 months ago.
what is your car ? year, make, model , and milage
1987 chevy cavalier, over 100,000 miles
when it comes to side terminal batteries that are having trouble starting/ staying charged, I always suspect corrosion at the terminals. I will clean those before looking at anything else.
Thats what I hoped was the problem but I cleaned them when I started having problems and there isnt any corrosion.
Check your charging system.
Use a DMM to check for parasitic draw.
