    Using a voltmeter

    Measure the voltage at the power supply then measure it at the terminals on the reactor.

    If they are within 0.5V then proceed to measuring the voltage at the plates.

    If that checks out within...

    Your materials will have to change. Stainless that you use for HHO will not work and will end up rusting. Nichrome or nickel 200/201 is the material of choice and is very expensive by comparison.

    According to what I've read, rail voltage is basically the voltage read at the filtering or stiffening cap(s) connected to the source pin and +. In this case it would be ~14VDC.
