So my truck is running on battery only currently. The truck has a new alternator, the back of it is magnetized. I thought the wiring might be wrong based on the condition of the wires in the rest of the truck and I was comparing to my bosses 66 mustang alternator. I used google to confirm that at least a few other people out there have the alternator wired up like the 66 mustang. Before you tell me how off base this is I would like to remind you Ford was still using a lot of components 12 years later including the alternator and voltage regulator.

Anyway I accidentally let the magic smoke out because it turns out that the orange wire isn’t Hot but was actually a ground and so I put power directly to the ground .
Here are my questions, the black wire is actually power and is spliced to a yellow/black wire. This looks like a factory crimp, the fusible link was right on the starter solenoid and now the truck is dead so I assume I have an ammeter somewhere. Would the link have protected the ammeter as well?
Is the tan wire the field wire?
what information do I need to find the correct wiring diagram for this truck? This all started because it isn’t charging whatsoever.

The white wire is the ground

Here’s the splice from the power wire

So the orange wire is going to the ground terminal, F of the regulator going to the S terminal and big cable going to B terminal?
