    Hi folks. I posted this question in the general "Technical" forum but perhaps it belongs here. I'm grateful for any feedback. My 1978 Ferrari GTB starter turns over quickly and very strong when I first start the car when the engine is cold. However, after driving the car for awhile, warming it up, turning it off, and then trying to restart it, the starter turns over very slowly and sluggishly. My thoughts range from "oil that becomes polymerized when it's hot," all the way to "bad starter that's succeptible to heat." Wondering if anyone else has seen this, or has any thoughts before I embark on an oil change and a starter swap. Thanks for any feedback. -Joe

    Sounds to me as if your starter maybe getting hot. Should have the heat shield correct?? 700 miles away from home at the moment so I can't just go out in the garage and check.
    I am just throwing a guess out there, had this happen to an old Ford we owned years ago.

    I would make sure battery terminals are tight and clean, make sure battery to chassis earth and chassis to engine earth clean and tight, I think you'll find it's a starter motor at fault though

    Forget the oil change...unless the car is due for one anyway. ;)


    I agree with the above post. It's either a faulty connection/cable in the start circuit or a problem with the starter itself.

    check the voltage ( plus and minus separately ) at the starter, then you see where the problem is.
    if all ok then the starter is going hot or to his end.

    Not sure if helpful - but had a similar problem on a much newer car. It was the plates on the starter that were getting dirty. Once warm, they would dilate and dirt would not allow them to move/start as easily

    Just in case helpful
