question, but is 12 volts really 12 volts? I'm asking because I'm
installing tortoise machines and in checking some of my old 12v DC power
sources, I see that they actually measure about 16 v DC... even though they
are labled as 12 volts.
It seems odd that three 12 volt sources would all measure about 16 so I'm
wondering if a 12 volt power supply is actually something other than 12
volts... much like a 2x4 is really 1.5 x 3.5.
My concern, of course, is that I don't want to burn out a tortoise machine
using a 12 volt power supply that is really 16.
