One wire alt. question

Hello all- Just signed up and know someone here can help,so here goes. I just put a 302 in my old 61 fairlane, and now have a one wire alternator to hook up.What size wire should I use and I have been told to run it straight to the positive post of the battery. Is this right? Or should it go to a certain side of the solenoid mounted on the wheelwell? Thanks in advance for the help

One wire

Actually the heavier the better ,if you use a universal 4 gauge cable much like the cable you now have on your Fords' solenoid to starter with 2 flat ends.Hook one end to the alternator and one to the positive battery clamp bolt,be sure you detatch your neg ground cable first.

I always use a 8 guage wire and run it to the positive battery terminal on the starter solinoid.

Ditto Henry Highrise post to the 8ga (or 6ga)wire and to add one more point - remember that a single wire alternator needs an engine rev to start the charging process - a throttle blip to 1500-2000 rpm will usually do it.
