    Well, system up and running. I went over to Radio Shack and picked up a project box (remember them?). I did some major surgery on the box to cover the isolator terminals and most of the relay. I installed a dash indicator light when isolator is activated. I also have a pillar installed volt meter that reads everything off the ignition switch (ignore the warning, there is a red light that comes on below 11.5 volts) 105.png 106.png 107.png

    Having this two battery system is great. Starting voltage has not been below 12.3 volts, normally 12.6 - 12.8 starting volts now, and I have been doing short trips last couple of weeks. Before I would drop to as low as 11.5 volts (no start) with short trips.
