Here is a product found on Amazon that I just bought recently. It helped almost instantly. It gives you voltage readings and had a green light to indicate if all is okay. Starts blinking if voltage falls to low. Also has usb charger built into it for charging phones or maybe a GPS unit.
Installed this until I have time to install a "real" voltage gauge. Found voltage dropped way to much when I turned on fresh air fan (dropped to 10.1 volts). Yes, there is a problem with the fan wiring, have another post looking how to solve it on the board. Thought I smelled something burning. Turned off fan and voltage went right back up to 13.8 volts. The blinking light caught my eye right away. Might be even better that a voltage gauge. Only $12.99 plus tax. Don't normally stump for products but I think it was a post on this website that got me going in that direction a few weeks ago. |

Slick!
My stock gauge was showing about 10.5V. Had me a bit worried on my last drive. Not driving as much as I used to. Trying to keep the miles down. Everything seemed to be working fine. All lights at good levels. Got home and put a meter on the battery while engine at idle. 13.9V, so my gauge is off. |

More likely you have resistance in the wires due to a bad ground somewhere and its showing less voltage. I don't think there is much calibration to do in a voltmeter. Zach |
