I had my dealer change out the starter motor in my 1990 318 last summer. I had the dealer put in the starter after reading threads on how difficult it was, and indeed the dealer took longer than he thought because of various problems that came up (all of which have been posted on threads here in TBN land).
I was doing a mid-season clean and look-see when I saw that the battery cable was put on in such a way that it was rubbing agains the chassis. I suspect that the cable was put on the solinoid before the motor was installed. So I'm posting some pix and telling my story in hopes that if someone has a starter motor that gets changed, they can watch out for this little problem.
In the first picture, you can see where the lug should of had the cable attached coming out of the top or bottom. It was pre-attached coming out of the side. So the shrink wrap on the ring is rubbing against the chassis frame. Note that the wire and ring-lug are bent in so much that you can't get a socket or wrench on the nut anymore (without removing the engine and starter again, which is where all the "hard stuff" happened). The battery wire was also outside of the shield instead of under it. I'm sending these pix to my dealer along with a "scolding". They got it wrong and didn't go back and fix it or solve the problem.
In the second picture, you can see where I slid a piece of fiberglass perf board in between the ring lug and the chassis to keep things insulated. The ring lug bent in a bit more- it was a tight fit. The battery wire is now running inside the chassis under the air cowling.
The last picture shows a bit of RTV that will keep the perf board from falling out due to vibration. The board and the ring lug are glued together.
So if you or a dealer are changing out the starter on a 318, make sure you get the battery cable on there the right way. The sparks would be flying if this had shorted out before I caught it. This is also why I do a mid season "take of the skin and look at stuff" check :thumbsup:.
