My 6x4 starter kicks in when you turn the key to the run position and stays kicked in. The starter should kick in when the key is all the way to the right in the start position. But starter kicks in and stays running when the key is in the run position. What the heck? I this my second 6x4 so i can swap parts as needed, New key switch. What the heck? could it be the starter solonid?
