I was finally able to get back out to the truck but still couldn't get the ammeter to work, more advice please!

When I moved the wire that runs from the bat term on the solenoid to the ammeter (charge) instead of the ignition switch the truck wouldn't start.

Here is a description of the wires from the generator, starter solenoid and ammeter.

The 2 wires from the generator terminals go to the F & A terminals on the regulator.

The wire from the battery terminal on the starter solenoid goes to the bat term on the ignition switch and the other wire on the solenoid is going to the center post (hot?) on the ignition switch.

The charge side of the ammeter is connected to the B term on the regulator and the Discharge side is connected to the horn term on the fuse block.

Should I leave the wiring as it is and add a wire between the + ammeter post and the bat term on the ignition switch?

Or should I leave the current wiring and run a second wire from the bat post on the starter solenoid to the + ammeter.

Or should I make other changes?

Thanks for hanging in there with me.
