I'm not very Knowledgeable when it comes to wiring so I could use some help on this. Here is a diagram I made up. Can someone look it over and see if it's correct?

You need an incandescent indicator light, a diode, or a resistor in the wire between the I terminal of the key switch and the #1 terminal of the alternator. If you don't have one of those the alternator will back feed the system and it will continue to run after you turn the key off. Below is a diagram from the Ferguson site showing the proper wiring from the I terminal and info on the diode, light, or resistor required.

Move the diode to #1 pin on edge of alternator as Jim says. White band toward alternator.

There should be no diode between alternator output and ammeter. As it is now the system will not charge. The diode is a one way device, and with white marker toward alternator it will block charge from going to ammeter.

Rest of wiring looks correct

Looks good except for the diode as said.

Do you know what coil it has?

If it's a true 12v (3 ohm) coil you are good.

If it's a 6v (1.5 ohm) or says resistor needed, it will need a 1.5 ohm resistor on the ignition side of the primary.

Yes, its a 12volt coil. Just purchased it last week!
