The jingle is actually a whistle...
If you were driving past the stadium maybe the Cowboys Cheerleaders were whistling at you?

Holding the shifter did nothing I guess.

Remove the belt and drive up the block to test.

Does it make any noise sitting still while revving the engine? Maybe your wife can help with that.

I immediately thought of the accelerator rod in the tunnel, bushings go bad

Martin,
I pulled the belt off and the whistling stopped. So would that mean it's in the generator or fan? And would it be ok to drive it? I mean, I have been driving it, but I don't want to screw something up. What could it be? I just had the generator overhauled a few months ago.
Thank you,
Glenn

I’d try an automotive type stethoscope to listen to generator while revving the engine a bit. Maybe the rebuilder would do that if you visited them

Great idea!! Thanks Martin, I'll call him. But you think it's still ok to drive? I'd hate for it to crap out on me somewhere...

Nobody can predict what will happen. Of course you must have the fan working to drive farther than down the block or you will definitely overheat and put a big hurt on your engine. Fans have been known to explode and that can take out the oil cooler and destroy the fan shroud. If it is the generator you should fix it quickly.

This is a case where not driving the car might save you a lot of money. If your mechanic is not far away then you could drive the car at very low rpm to get there but nobody knows when or if your car is safe to drive.

Make sure nothing is stuck in the blower reach around the shroud and check make sure the engine is not running!!!

Still good to try it with the belt off in case it is generator noise or somehow related to the fan or air from it.
My friend has an SC and his engine whines/whistles like a jet engine when under acceleration.

Sounds like the cooling fan is out of balance. I have mine tack welded and balanced by Rimco.

"Generator overhauled a few months ago."
It's possible that the brushes haven't seated yet and are making the sound.

Sometimes just slightly changing the fore and aft position of the fan will result in a whine...or diminish/end the whine. Possibly the fan isn't correctly shimmed within the shroud.
You can use a stethoscope, ( or even a long screw driver), held against the generator, to determine if the noise is from within it. Just use caution when leaning near a spinning component...especially if you have long hair.

You can grab hold of the top of the fan housing with the engine idling and move the housing fore and aft and you might hear a change in tone.

You can also re polarize the generator and see if it rings when the generator spinning like a motor.
