I change my alternator and have a good battery but wen I try and crank it everything click but won’t crank at all
one hard click is an indication of a failed starter. Several or repeating clicks is an indication of a weak battery or poor connections. Just because your lights come on or the radio works does not mean the battery is good. The starter requires about 250 amps to turn over. The radio requires less than 10 amps to function.
