Battery relocation & 1-wire Alternator (Powermaster)?

I tried searching but I couldn't find the answer.

I have a Powermaster 140amp 1-wire alternator and I'm going to relocate my battery to hatch. I've seen the diagrams (buffhomer's site) about running a 2 gauge wire from the alternator to the battery and a 1/0 gauge wire from the battery to the starter solenoid.

My question is can I just run the wire from the alternator to the starter solenoid and a wire from the battery to solenoid? The reason I ask is that I already have a wire from the alternator to where the battery use to sit and it would be an easy hookup to the solenoid.

Would that work or should I run a wire from the alternator to battery?

Thanks!

Yes, you can run the alternator charging wire to the starter relay where the positive battery terminal is located. There is nothing wrong with this setup as long as you use 1 gauge wire. You don't want to use smaller wire because the alternator is pushing up to 140 or slightly more and 1 gauge would be required to maintain a consistant current level.

You sure can and it'd work great. Just remember you won't be NHRA legal if that matters.

So is the only reason to run a wire from the alternator to the battery (battery cutoff switch) is to be NHRA legal?

It will still charge the same whether the alternator is wired to the solenoid or battery?

Thanks for the replies!
