I have a INNOVA Pro Digital Timing Light (DIS) should be a pretty good source of a votage meter. But I do have a couple other DVOM I can try.
This is the reason I ask. I replaced my voltage regulator with a solid state unit and watched as voltage climbed past 20 volts.
I hooked up another cheap harbor freight meter I had laying in my toolbox and you can see the difference - Problem was, the battery in the other meter was almost dead.
