Is it acceptable to connect the battery charger hot wire leads to the battery terminals at the "Off -1 -2 -Both" switch to shorten the length of the smaller gage wire or do the leads have to go directly to the battery post with in line fuses? Assume the leads would be fused at the switch connections and the battery cables from the battery to the switch are much larger gage wire reducing the voltage drop over the length from the switch to the battery. I see on Maine Sail's "installing a battery charger" he runs directly to the battery but I'm curious if this is an acceptable alternate practice?
