Starter issues again!

Done some testing this afternoon. I checked the battery i got 13v i got 13 at the top post on the relay and 12.6 on the bottom post (when tuning the key) 0 when not. So the relay is working. I have 13 at the starter on the hot side and 12.6 on the solenoid side when turning the key. The neutral safety switch is working because I don't get a click when I turn the key in gear. Any ideas other than a pos starter? Lol
