OK one more question, but it's still related for the most part. Hope you don't mind!
My alternator is a 90 amp Balmar with ARS-5 external regulator. I don't know what gauge the charging wire is currently. Regardless, what should it be for a 5 foot run to the house bank?
According to the Blue Sea chart that Maine Sail posted, that looks like 4 AWG. But when I use the circuit wizard on the Blue Sea site, it comes out as 6 AWG, even up to 100 amps. Of course it will usually be a lot lower than 90 amps from my alternator.
So how do I size the alternator wire? I know the fuse will be MRBF and I'll size it according to the alternator wire size.
Thanks for the additional help!
