=========================================

I would not recommend a diode isolator to anyone unless they have the
expertise and ability to connect an external sense wire to the
alternator. Without external sensing your batteries will never come
close to being fully charged because of the voltage drop (~0.6 volts)
in the diodes. Lack of voltage drop is the big advantage of
combiners.
