POOR MAN’S VOLTAGE TESTER
A NEON lamp will not light-up above 105 volts. We use neon night lights in our RV to detect low voltage in our rig. We try to stay above 107 volts, and below 130 volts.
We have four circuits in our rig that we monitor. The bath, kitchen, bedroom and living area.
Lowe’s, Home Depot, Ace Hardware and True Value hardware stores can special order the Neon NiteLite Value Pack of two lights. Amerelle’s part number is 71050. We also have found this item online. Any NEON light will serve this purpose. After freight charges, we pay around $10 for two packs of two. Other brands are also available.
After 8 years 3 out of 4 of these lamps are still working well.
Walmart is selling digital voltmeters at a discount in Cottonwood, AZ. – $40 for a item worth $60.
Happy Camping,
