Earlier this year I posted a question about my 96 Jetta's dim lights (when the car starts, the lights [dashboard/headlights) are dim until the engine goes above 1500rpm; After that, all is bright even if rpms go below 1500). Posters said the alternator was suspect.
While I don't fix big things myself, I do save hundreds by buying the warranted parts on-line, and my mechanic puts it in. Is there anything else I should get besides the alternator? Some other little boxy-whatsit that is always replaced when the alternator is replaced?
Thanks for any advice.
