Not Ranked
Rodney,
I'm still building my kit (not a SPF, a West Coast), but have changed from a 3-wire system to a single wire Powermaster 140 Amp alternator. Simply run the single heavy wire to the battery side of the starter solenoid on the firewall. Powermaster does not recommend or require a fuseable link for this wire. Then, I disconnected my external regulator and removed it altogether.
Power to the interior on my kit is from a couple of wires that run from the battery side of the starter solenoid into the fuse panel through fuseable links.
That's it. It was really simple and works fine. Just need to get the alternator RPM above the speed threshold for it to self-excite. There's also the alternative to wire it like a 3-wire alternator, a Powermaster exclusive, apparently.
If you don't have your alternator yet and want to see Powermaster's installation instructions let me know and I'll either fax or scan and email to you.
