hey I've plenty of experth knowledge, I've lived there on & off for a while in the summer months :-)
Back on track however, as my 2 photos (above) clearly show, there's no impedance or such from a quality electrical battery isolator
, or it's connections with-in the charging circuit, the 2B&S cable will only drop O.O2v between the 2 batteries that are 4 meters apart anyway, and any standard alternator should be capable of charging @ >13.8 volts, which will ensure the accessory battery receives adequate charge.
However, and yes this is where the *but mine won't* comes into it ....
they MUST use an AGM battery;
AGM's will fully recharge faster
AGM's have lower internal resistance
AGM's can be fully charged at a lower voltage
AGM's are capable of accepting a much larger current
(these are also the reasons AGM's work more efficiently in solar power
