Well after 195k my stock alternator has finally went south in my 95 Caprice. I'm thinking about having it rebuilt to a higher output. I'm also thinking about having the alternator housing and the engine accessory bracket powder coated black while it's apart. Is that a bad or good idea? I've read that it might be bad to coat the housing because it won't dissipate heat like it should. Also at that time I'm going to do the big three and upgrade to a corvette starter.
