- Disconnect charging lead wires from vehicle alternator. This means all of them
- Run a huge wire from alternator to an ACCESSIBLE Circuit Breaker rated 200% of rated alternator output amperes
- From this breaker continue to HOUSE batteries, same gauge wire
- With a 130 ampere alternator I would use FOUR GAUGE WIRE, the entire distance
- With a 270 ampere alternator TWO AUGHT wire the entire distance
- Run an equivalent gauge wire from the engine block to house battery negative
- At house battery positive use minimum 100 amp rated separator I would choose 200 amp and run the charge lead wire to the disconnected original alternator output wires.
How can wire sizes be quoted w/o knowing length of run ?
My current house batts set 12 feet from my alternator.
In my last rig 2 6'ers sat 3 feet from the alternator.
But then, if engineering calls out 2/0 wire for everything, its hard to miss,.....I guess !:R
