I bought a new starter and it went out within a year. Bought a new one and had it installed. It lasted 5 minutes, and they had to put ANOTHER new one on. No probs after a year now, but I am just saying even NEW ones can be junk. I assume you replaced JUST the solenoid? You obviously have only 2 ways to hook it up. If one is wrong then there is the other way, but what damage can be done is unknown to me. I wish I had a wire diagram for you, but I don't....I do know that there is a huge amount of current going through those cables which can get pretty warm quickly, thus why you never crank for more than 5 seconds at a time. I'll look through my manual and see iff it shows which pole is what...BRB
