Voltmeter ?
I just installed a digital voltmeter, a 5 dollar unit from Amazon. When I first push my momentary switch to turn it on the meter flashes 6.78 then shows the volts. Whats the 6.78?

I wouldn't know if mine do that or not, because they all stay on 24/7 no switching. Right now I have 7 cheap china voltmeters burning in various vehicles, half of which have been burning for 2 yrs now. All are quite accurate, and not 1 failure in a total of 12 that I have purchased over 3 yrs.
