I swapped my Y-Block generator for a one wire alternator (12 V system). I swapped out the original dash guages for new technology original looking gauges and sending units.  Idiot lite (charge) is now a volt meter. Instructions say to wire one side of the voltmeter gauge to ground and the other side to the accessory side of the ignition switch. First, does it make a difference which side of the volt meter you ground and which side you hook to power? Second, if the only wire is from the accessory side of the ignition switch, how is it reading the voltage?
