2010 4.6 Starter fuse blows randomly
This is my first post so pardon any mistakes. I have a 2010 4.6 that just had the starter replaced. Prior to that the #13 fuse (30 A starter fuse) would periodically blow, I would replace and it would be fine for a while then blow. Figured before the new starter it was the selenoid causing the issues but still having the same problem after the new starter has been installed. Had the truck towed to the shop, they replaced the fuse and cannot recreate the fuse blowing after 50 or so starts. Before it was towed I replaced the fuse 3 times and it would continue to blow. In my garage I park against a step could that be causing issues? Thank you in advance for your help.
