Alternator Wire Size

Post by rbsWELDER »

What is the generally accepted wire size to run from the alternator to the battery?

Thanks,

Yeah, 8 ga. would be great! I would say 10 ga minimum. That's what I'm using on my 100 amp alternator, with no problems so far. :P

Thanks,
What size alternator do you have? How long is the wire going to be?
NOTE: The distance in the table is both directions or round trip.

If you are running a 60 amp or higher do not use an amp gauge..use a volt meter instead....Dewey

I think Rick has a chart for everything. He needs to post a picture of his wiring under his seat.

Per Jesse's request, here are 3 pics of my wiring.

Notice how small the battery is, it's an Odyssey PC-680. Laying on it' side, it's
less than 3 inches tall.
