Soo i got the starter tested at autozone. Everything worked. Hooked it to my car. Thr car had no power. I changed the battery terminals. I got a little power. Took the battery and got it tested, the battery is fully charged. Whats the next step because i am at a loss.
Grab a set of jumper cables. Connect the negative side between the battery negative and a good ground on the engine. Any change? Next take the Positive cable and connect it between the battery positive and the battery power connection near the fuse box. Try it again. Any change? If either one makes a change then go to the other end of the cable on the car and clean it and try. The cables corrode at both ends.
