I'm wondering how the Argofet distributes the current to each bank. I have three banks on the boat each regular lead / acid. I have been checking the charge current from the alternator and it looks like when the alternator is providing 40 amps it all flows to the (large) house bank (output #1) and to the start bank (#2). The #3 bank, used for the bow thruster only gets 2 to 3 amps. This is resulting that the #3 bank is always low. The cable between #3 and the Argofet is a beefy 2/0AWG but much longer then the other 2.
