Sermon Subject: Battery wont hold charge?
I just replaced the battery on my 76 2002 because the old one was shot. It was having a hard time starting( not enough power) i put the new one in and it started great. BUT after about a week, it started losing power again. I took the alternator out and it checked good so now i think it might be a ground or a relay. When i take the battery out and give it a full charge, everything is fine. when it starts to lose power and i take it out, it is down to 30-40% charge on the battery so im guessing it is not charging when i drive. Any ideas?
