I'm no electrical genius. Now that we've established that, here's my problem.
I installed a Yandina combiner in the electrical compartment. I wanted the power source to be the PD unit which would charge both the house battery (up front) and the genset starting battery (out back). I used an isolator (which checked good) as a mounting point for the wires: PD to the center and each battery on it's own lug. To each battery was a lead from the combiner and the ground was grounded.
Even before I fired it up, it didn't seem to make sense. The combiner will cut in or cut out when it senses a specific voltage. How can it sense anything other than the output voltage from the PD unit? It will never combine as it should.
So how would you place a combiner so that it sensed raw battery voltage as opposed to charging voltage and actually cut in and out properly?
Or, is the wiring correct, but I was dealing with batteries that were close to fully charged?
OR, should I forget the isolator altogether and merely try to hook them up directly with wire nuts?
