Is there any way to calibrate the car's voltmeter?
I have a 95 Cadi DeVille; it's voltmeter reads 13.5 when my multimeters measure 14.7. I
know it is just an anal question, but I just wanted to know does anyone know how I can
calibrate it to read the correct reading? I mod the cluster to read as a Seville model
because DeVille models don't normally provide voltmeters. Even if it means creating a
small calibrating device to simply give the correct reading.
Is it a needle gauge..analog....that maybe you can spin the backing, or the piece with the numbers? To where it's accurate? Just a thought, I dunno if it works that way
check this out if you dont want to replace it >http://www.bobsspeedometer.com/1/120/index.asp
