Around here, I would remove it and take it an electric motor shop. Every medium size town has one but they are often in the sketchiest part of town between the discount liquor store and the hubcap/used tire store. Take heart though, as most of the shops are run by a 1000+ year old man that built the shop in an empty field full of cows...the urban decay came later.

All kidding aside, these shops are always off the beating path and cater to a weird combination of old car/motorcycle nuts, industrial clients and antique fan enthusiasts. It usually is a grump old man that runs the place but that is because not one else wants the job. I have NEVER had starter motor or alternator rebuilt by such a shop fail on me...ever.
