Ok here’s the scoop. I bought a 12v analogue volt meter and want to use it for my 120v pack. According to my “ meter” book to find the value of a meter one divides the face value movement of the meter by it’s resistance than multiplies this by the desired use. The resistance of this meter is about 500 ohms and the swing is 18 hence 500/18=27.77… x 120volts=3333.3330hms ( or3.3k) – 500 ohms for the internal resistance of the meter =2.8 kohms needed to balance the meter. This I did with 5 wtt resistors and hooked the meter to the pack ( my DVM read 152v) and to my delight the 12v meter hung at about 16…… for about 5 seconds than poof!!! Up went the resistors. Fried to a crisp. What gives! Any ideas? I don’t have the electrical training to figure this out, and I’m delighted with the presentation of the meter in my dash……. Any help on how to make this work would be great…….. tesaract, Major, come on guys……….. thanks. Lou-ace
