99% finished putting this together but a couple questions- The jumpers for H2 and H3, what are they used for? Also in this area, how does the Voltmeter fit here if those jumpers are there? I want to put the voltmeter in, so where is the best spot to solder the wires? Was just thinking about this now, but is H2/H3 actually solder points for the Voltmeter, obviously depending on which direction it is installed?
