Shoestring Digital Voltmeter

A 2000 watt Honda generator is used on SummerPlace to maintain the batteries while on cruise but the analog panel meter doesn't help much. I wanted a digital meter but a replacement panel mount unit is ~$175 if one can be found to fit. Harbor Freight often has digital voltmeters on sale for three bucks. I wired this one up to a handy spot in the closet.

Now I can watch my batteries charge up without my checking account draining down.
