VOLT ?

[98whitelightnin]

My volt gauge goes up to the normal spot, just a hair over 14 but my scangauge II reads 13.5-13.6 volts. Is this normal?

Using other instruments on my truck, it seems the trucks readings are approx. and the external instruments are more accurate. I question this before and double checked using my friends instruments, my instruments and compared to the truck. Externals were the same with the truck slightly off. I wouldn't worry about it, but if it's accuracy I'd go with the scan gauge.

My volt gauge is maxing out at 18 volts, but my scan gauge and test fluke meter reads 14.7 volts. I have been fighting this for a few days. Can't figure it out.

Just remember that the Scan Gauge is only saying what the computer tells it. The best way to find out for sure is to use a VOM across the battery when the vehicle is running.

There is a few things here to remember...Volt gauge is getting the information from the CCD network just like the ScanGauge II. Now the mechanical needle could be out of position. Or the Instrument cluster is not translating it accurately. :shrug:DVM at the batteries is the best bet. Yes. Even my ScanGauge II vs. Dash shows 2 different numbers as well. Worse on the 96 than the 02.
