Blower Sound When Connecting Battery 1963
I have a 1963 327 / 250 hp automatic. On my battery I have one of those Green disconnect *****. I needed to charge my battery, using a wall charger, I positioned the Green **** up (not activating the circuit from battery), I connected the red to red on battery / charger and black to a steel part on engine block.
I left the charger on overnight, when disconnecting the battery charger, and then turning the Green **** down to activate the battery circuit, I hear a blower type sound.
When using the battery charger in past this has never occurred.
Any ideas?

Was the ignition key in the off position?

Check the key position as indicated above - sometimes the key position doesn't exactly match the labeling above the key slot on these cars...
The only "blower" sounds you could possibly hear are if you have an electric cooling fan or the heater blower.....
63s did not have the rear coupe area ventilation blower that came in later year cars....
You need to isolate the sound - one way would be to pull the heater fuse...

Yes ignition key was off not in car, I waited about an 1 hour, turned green **** down to try to start, and now the blower noise is gone, never heard this before. Thank you for your quick response!
Car is a 1963 327/ 250 hp, automatic car. Bought it at Carlisle last year.
The other day while driving, I stopped at a light after driving 20 minutes and car stalled while in drive, I was able to start it, came home, let it run in park then placed it in drive car stalled again after a few minutes.
I did a test on battery: engine off 12.80, engine running 12.60, after 6-8 minutes 12.55 -12.54 with door open, radio on, engine off after running 15 minutes 12.69-12.70.
had car running yesterday for about 20 minutes in park, and the 15 minutes today no stalling.
previous readings a year ago. engine off 12.90, engine running 14.97, engine off after running 13.25.
Is it possible alternator charging battery?
THANK YOU again for your time, the Corvette Forum is outstanding.

Just a gues here. If the battery was connected, the accessory circuit was on and the heater fan switch on, AND the battery very weak, a low power battery charger would not likely have produced enough current to both charge the battery and run the fan fast enough to be heard. In fact, it likely would not have even charged the battery. If you subsequently disconnected the battery at the green switch and then charged it, it would run the fan when it was reconnected.
The KEY here (pun intended) is that 1963 Corvette ignition switches have the ACC position in a different spot that modern cars. If you did not know this you could have left the key in the ACC position rather than off. That would have drained the battery. The key can also be removed in the ON position and create the same situation.

If you put a multimeter across the battery terminals at a fast idle and you don't read between 13.8V and 14.2V then your battery is not charging.... Any autozone can load test your alternator on the car but my money says its not working...

Ok thank you, I had the charger on battery, with green **** off (not in a running position).

Thats what was I thinking also. Could driving the car for 20 minutes if the alternator was not charging the battery cause engine to stall?
Frankie you helped me last year concerning removing a corroded front turn signal bulb!

Get your charging issue addressed -- and you may find your blower noise and stalling clears up...
If not, we'll go from there... If the alternator is not charging then you are driving strictly on battery voltage - its a myth that these cars are happy running on just 12V - they "like" the higher voltage that the alternator provides...

Frankie,
thank you again! Zip Corvette parts has an rebuilt alternator 42 amp I believe mine is 37 amp.
If I take the Alternator out can it be tested at AutoZone?

Worst case the alternator and voltage regulator checks are in your Corvette Shop Manual...
