I spent years working in underground coal mines... it would amaze you how many things you can get to work by beating the hell out of them with a hammer...
or ask my brother, he carried a hammer in his VW jeta... to start it you had to climb under and beat the solenoid with a hammer. Why not change it? Did you ever try to change the starter on an old jetta? You have to pull the header and half the other crap just to get to it
