While driving around in my 66 GTO tripower, stopping here and there, the third time I started it up it barely turned over. Battery is good, always starts ok.
The strange thing was that on this start, the radio, tuned to 98.5 FM, lost the station when the engine caught. Something strange electrical?
Thanks.

If you have a modern radio with memory, the battery voltage during cranking probably drooped below the voltage necessary to keep the memory alive.

George is right a voltage drop caused the radio problem Have your starter tested sounds like it is drawing too many amps when hot Have your battery tested also It can have 12 volts but not enough amps Also check cables and starter wires for cleanliness Any corrosion put new cables on Clean posts on battery install corrosion pads on battery Check battery water Check alternator output with EVERYTHING ON Be sure all ground straps are hooked up from body to engine If you have headers you may need a heat shield for the starter If battery water was low or three years old replace it now That should give you something to do today. Most auto parts stores Auto Zone Pep Girls can check all of this for free

Unfortunately, Pontiacs are notorious for overheating the starter, especially if you have headers or HO exhaust manifolds. Make sure that you have a heat shield installed on the starter. If this problem continues, you might want to think of purchasing a mini-starter. It is smaller in size and has much more torgue than the original. Some also have an indexable solenoid, which means that you can turn the solenoid down so you can hook up the cables after the starter is in place.
