i checked the battery and it was good then i take off the alternator and it was good. So i figured it had to be my starter so i take the starter off and go get it tested and they saidd it was bad it was not working so i get my battery checed and they charged it once more they said it was good. i bought a new starter for $150 and i connected the starter and then the battery and nothing happened. samething as before i would not start and all i heard was clicking. I have no idea what to check next any suggestions?
thanks guys
