As I stated in my introductory thread, I picked up a 91 750 last week with 9100 miles. The lady I bought it from said that it got to where it would only start when jumped, and so she got a new battery and the same issue happened. I immediately figured something simple was robbing voltage from the coils. I bumped the starter before handing over my dollars just to verify it wasn't seized. I'm pretty confident that I can fix anything. Eventually.
Looking at it last week, I tried to start it because I'm a dumbass and the negative terminal on the battery started melting. I had to grab tools, pull the seat, and pull the cable off, then let everything cool before taking the battery out. It wasn't until a day or so later that I realized the starter was still turning as I was pulling the seat. I was too concerned with the melting smell on my carport.
Other obligations (Mother's Day weekend getaway) got in the way of looking at it, but in retrospect I'm thinking that the starter has been going bad, robbing voltage, and my ungentle thumb overheated it, causing the solenoid to stick closed. This is just a guess until I look at it.
Not really asking anything in this thread, just rambling for a moment. I guess I've already got post-count envy.
