New user here. I am building a 56 Ford Panel truck. It will have a 460 engine. I'm trying to get the wiring ready...I am starting from scratch. It has an external voltage regulator with terminals marked I A S F. I need to hook the battery, starter, regulator and alternator up. Also The starter solonoid on the firewall. I know the starter has one side the battery is connected to and on the other side the starter is connected. What do the two in front marked S and I connect to? Is the S for the start on the ignition switch and the I for the ignition module? I know it's an involved question, but any guidance/advice is appreciated.
Thanks,
James

You've pretty much nailed it. The S terminal runs to the S or Start terminal on your ignition switch. When you turn the key to the start position, it puts current to that post and makes the solenoid kick ( pass the current to the starter thru the fat cables.

The I goes to the plus side of your coil. So does another wire that comes from the I or Ignition post on the ignition switch. The one from the solenoid puts pure 12 volts into the coil to assist you in getting the engine started easily. Then when you release the key to the run position, you are now getting your current to run the coil from the ignition switch. That one usually goes through a resistor or a resistor wire to drop it down to maybe 6 or 7 volts so you don't burn up the coil while you are running.

If you haven't already done it, I would suggest one of the many wiring kits like Painless or Ron Francis, especially if you are wiring the entire truck. It is a formidable job, even for those people who have done a few. These kits make it so much easier.

One of our smarter-than-me-computerwise-members will probably post a diagram for you to look at. (how do they do that??? ) But if you have any questions, just repost.


Good luck,

PS. Wecome to the forum. We need more Ford guys. Those Chevy guys push us around alot. lol

12 volts is always present at the coil, the resistor/resistence wire drops the voltage to the points.

Man I realy love the ONE wire alternater

the resistor will be between the ign and the coil. the coil actualy works on 9V
