  1. Carefully eying this right now:


    Went to go test drive it - car started and ran very well. Very smooth shifts, no gear banging. Mechanic who is selling it also did most of the work on it and had bought it from the previous owner when it needed some coolant system work

    Overall the car is clean, and looks like it was maintained well. The only thing throwing a red flag is the mechanic mentioned that he put a bigger alternator in and now the battery light comes on when you start the car UNLESS you blip the throttle slightly after it starts - after that no problems... Thoughts on that?

    Anything else I should be looking closely at?
  2. Control arm bushings, make sure the CD player works properly, why did he put in a larger alternator?
    Remove hardtop and check out the rag top.
    Just a few hints.
  3. Thanks I'll look into it

    He wanted to put the larger alternator to prevent battery issues in the future. I just don't understand why the light would come on like that. Next time I go look at it I will bring my voltmeter

    Not an expert - don't alternators sometimes have to be polarized when first installed? Perhaps something is causing it to have to re-polarize at startup? (Frequently I have no idea what I'm talking about!)
  5. Sorry, but that would be a red flag for me. I have never heard of anyone having to change the stock alternator to a larger one, and I've been involved in thunderbird forums for over a dozen years. My opinion, pass on that one there are too many good buys out there.

    If he's a mechanic, why not put in the correct alternator? No way I would buy that car when another one may not have those issues. Everyone selling used cars always has an excuse for why warning lights are on and why it's supposedly no big deal.
