03 Xtreme Fosgate Posted July 16, 2013 Report Share Posted July 16, 2013 I popped the hood on my truck to adjust my headlight and noticed a sizzling/hissing noise coming from under the hood. I thought it was the engine or cooling system at first since I was just driving it but it appears that it's coming from the battery. I have a 2003 Chevy S10 Xtreme,3400 underhood,D1200 in the cab,with an Excessive Amperage 300 amp alt. charges about 14.8 when first cranked then goes to around 14.4 once warm,battery voltage was resting at 12.89V when I tested it after hearing the noise from battery.

Smoove Posted July 16, 2013 Report Share Posted July 16, 2013 Did you test at the alt with a volt meter? I had a voltage regulator on an alt go out and cause the same symptoms. I was going as high as 18.6v when my regulator took a dump.

Smoove Posted July 16, 2013 Report Share Posted July 16, 2013 I would go buy a Autozone or something and have them run a battery tester since your voltage is good.

Nathan @ XSpower Posted July 17, 2013 Report Share Posted July 17, 2013 If the battery is whistling then I would guess you have some high voltage going to it at some time. That is primarily the case for having one whistling. At some point the battery gets too high of voltage and it causes the vent covers to raise up, which can cause a whistle. Did you smell sulfur? If not then you are probably still good to go. How old is the battery? Quote Link to comment Share on other sites More sharing options...

I've got to meet with Excessive Amperage to clamp my alt so I'll check for voltage spikes while it's under a load.

03 Xtreme Fosgate Posted July 17, 2013 Author Report Share Posted July 17, 2013 I'm taking my truck to excessive amperage to let him check my alternator so I'll find out if it's spiking or not.

Kyblack76 Posted July 17, 2013 Report Share Posted July 17, 2013 I'm taking my truck to excessive amperage to let him check my alternator so I'll find out if it's spiking or not. Put a meter on it... Use the MIN/MAX option.. go nuts Quote SMD SUPER SELLER The Burban Build Blazer Build sold Acura trunk build sold Link to comment Share on other sites More sharing options...

Put a meter on it... Use the MIN/MAX option.. go nuts That's my plan,probably going to do that this weekend myself to see if I see any spikes. My DMM doesn't have the min/max feature though,I got a deal on a meter kit at a supply house a few years ago when I worked for an electrical company...
