Alternator wire gauge
My alternator is currently set up to charge my starting battery through the starter on the engine. I'm going to hook up an Echo-Charger, so apparently I need to re-wire the output of the alternator to my house bank.
My question is what size wire do I need for this? The current wire making the short (< 1ft) run to the starter is quite small (12 gauge?). If I'm going to wire the output to the house batteries, do I need to buy a larger gauge wire to make the run ($$$)?
The total run will be around 8 ft (via a bus bar). I think the alternator is a 55 amp.
Also, do I need to include a fuse in the wire? (if so, what size?)
