It should be 14.2 -14.5 v when running

2x 14ga charge lines right to the starter relay

14 Gauge wire is only rated for 15-18 amp... Using two i dont know if that doubles to 36 or not...  Im a little suspicious of the 2 x 14 gauge wiring.    On my car I ran a 10 Gauge wire from alternator to starter relay.

Years ago I installed a 400 BB into a 92 Dakota in place of the 3.9 V6.  That truck had a wire running from the alt to the battery from the factory.  I reused the wire on the BB.  That wire was huge.  It was over 1/4" thick(with the insulation).  What is that...4 gauge?  I saved that wire with the factory connector.  If I can get it to fit my Dart, that's what I'm going to put on there.

or use a smaller pulley on the Alt if anyone makes one so it will turn faster

This has been an idea of mine BUT just can't seem to find a workable pulley.

I agree with CP. 13.5 is kinda low. Should be over 14.

You can't put a wire too large on , on too small so bigger is better

Exactly where to get a workable pulley , Brad could probably tool one up !
