HELP, Wiring Problem

A bit hastily drawn

Starter relay: Some of these are wired "different" but I'd bet this is a standard Ford type. This has an "I" terminal and an "S" terminal. To find out, do this:

Clip lead one mounting ear to a battery. Take your other lead and hook to battery positive, and hook the opposite end first to one small terminal, see if it clicks, then the other. If one terminal causes the relay to click, this is "S" With the relay energized, there should be continuity between both large terminals and the remaining small terminal. This is "I". It's purpose is to feed battery voltage to coil in start.

IF THIS DOES NOT work, post back

Ammeter: Just hook it up and try it. You will have a 50-50 chance, it will either read backwards or forwards, and if backwards, just reverse the connections.

Alternator / regulator: The "I" (indicator) terminal of the regulator need not be used with an ammeter. The "A" terminal hooks to "hot battery" the "S" terminal is "switched 12V" and F goes to field on the alternator. If the alternator has more than one small terminal, ignore them.

Your alternator output is the "obvious" large output stud

If you use something big for wire, like 14, I'd use either a 15 or 20A fuse, or just a breaker for "fail safe."

NOTE. If this is a standard Ford relay, I have the drawing labeled backwards re: physical layout: This description below is incorrect in one respect. It does not matter which large terminal goes to battery and which goes to starter
