One last item. Do not forget that the neg wire for the alternator is equally important in this circuit as the positive wire. They should be the same size. These are 1/0 UL1426 battery cable.


I find the best location for a heavy neg wire on these alternators is to the adjusting arm ear. What can't be seen here is the alternators temperature sensor, which is also very important, especially if feeding large banks or banks of AGM batteries.


At the time I did this article Electromaax did not offer these alternators in an isolated ground option, I generally prefer this, and they now can offer that as an option.
