climate control light flicker?

[buckyboy]

anyone ever notice the light on the climate controll(numbers) flicker?..also, what should the volt meter read?

Someday when I scrape up enough cash to buy a good oscilloscope (yeah, like I've been saying this since about 1993 or 1994), first thing I'm going to do is plug into the gage pod power feed. I want to see what kind of ripple is on that power feed and at what RPM. I'm not 100% convinced it's purely a low-RPM issue... I could swear I saw a bit of flicker on the gage pod lighting on the highway at 1500-1800 RPM at one point.

A nice capacitor hooked up through a diode/resistor combo should smooth that feed out, if it turns out to be just a little operational 'noise' on the feed.

My radio has done this since day one....

Yes, many cars have done it since day one, other are not so noticeable...I don't think there was a definitive fix...


also, what should the volt meter read?

That depends...ideally 14.1 to 14.4 Volts...but, that will vary depending on the battery's state of charge, engine RPM, electrical load (lights, big stereo, foot on the brake, windows going up, rear window defogger on, etc)...

Something I've noticed lately is that when I fire up the A/C and I'm standing at a stop light my volts drop down to just over 12. They go right back up to 14 with any increase in RPM, though. I'm not concerned about it, but there was a time when I'd hold 14 volts no matter what I did to the car. Is this just a sign of aging?
