Default High Pitch Sound??

Hello -
I bought my 1994 Corvette last fall, stored it over the winter, had a starting problem (which you guys helped me fix - thanks), I put a new battery in it just now, started right up but now...

...I get this high pitch sound coming from (I think) the engine area? I have never heard this before. It was intermittent. Being that it is 12:30am and I was just happy it started for me again I decided to call it a night and post about this.

Hoping some can shed some light on the subject.

Thanks in advance for any suggestions.

check the belt drive. I would be willing to bet either the idler or tenstioners is bad, or, the alternator has a bad bearing.

Remove the serp belt and start it up. If it stops, then you know it's one of the drive accessories.

Maybe the TURBO FAIRY visited you over the winter?
