So when i turn the key it just clicks and randomly when i try it will turn over just fine but i never actually started the engine because i would stop trying acter a few seconds but it only did that twice for me. If i try and turn it over 2 out of maybe 25 attemps it would turn over no problem like the battery has plenty of charge. the grounds all look good and the starter was fine before i had the harness redone. What could be causing this? and if it is the starter how can i diag that and know for sure?
