Hey guys I'm wiring up my engine to get it started (basically gonna be a temporary setup). I am running a duraspark II system and a ford alternator with 3 or 4 connections on the back. It has a stator, battery, field, and ground. Could I hook it up like the pics below and be good to go? I wanted to see what you guys thought first.
The wire gauge depends on two key items: wire length and charging current.
If you have a 100 amp alternator, I'd use a fatter wire for the charging circuit. If the run is very long (more than 3 feet or so) I would, again, consider bigger wire.
10 gauge will be fine if you have a short run and a 36 amp alternator. If, on the other hand, you have the high output alternator (65 to 100 amp), and you ever end up with a dead battery & jump start the truck, that wire will have to carry a big load for longer than normal...it could melt the insulation and that of any wires bundled to it.
