Hello everyone, Getting ready to convert my 860 Ford from 6V to 12V. I have it all mapped out in my head how I'm going to run all the wiring, just curious if anyone has a schematic they made? I will be using a 3 wire 12SI alternator with an amp gauge. With a 4 post starter relay. Thanks for the help.

Read this post. It has the wiring diagram for the 860 with the amp gauge. It also explains changing the 3 post 860 starter solenoid to the 4 post solenoid.
If you need help understanding the conversion you can read this. It also tells you how you can use the generator mounting bracket to install the alternator.
Sorry that is the best I can do right now because I’m on my phone and all my diagrams are on my computer.
What are you calling "two solenoids"?
The starter push button is nothing more than a grounding button. It grounds the wire when pushed. Because of this you need the correct relay. Ford part # 311006. This interchanges to Napa ECH ST542 or BWD S103. Armed with these part #'s you can get the proper relay at any parts store; but they may have to order it.
The relay needs keyed power to one small post and the other small post gets hooked to the starter button.
Now for the complete wiring diagram.
