That's in essance what the drawing I provided shows, wired inline between the battery and the load. But I'm not sure I'd have all those power wires bolted togehter and taped and just hanging, they need to be on the solenoid post.

So i need to Come off the always hot side of the ignition To the Gauge Through The gauge Out to the + Side of the Starter Solenoid now this also isolates the starter out of the circuit. After that see that the discharge goes neg reading if not reverse the wires right?? & I should not get any arc welding or fire?

Honestly, at this point, I'd take thet ruck into an automotive electrical shop that can ascertain your wiring and power distribution and let someone who understands these circuits hook it up.

NO Problem. The reason I suggested that is because your truck could be wired and configured many ways - thus the 8 different sets of instructions. It's tough to give someone accurate instructions when you don't know what that configuration is.

Actually if you are just looking for a charge indication, and the gauge will cut off the power between the ignition switch and starter solenoid, just wire it in parallel to the current wire running from the "Batt" post of the ignition switch and the Starter solenoid It should work like that.

So, just disconnect the negative battery cable from the battery,
Run a wire (12 gauge will be fine) off both posts of the ammeter.
Connect teh wire on the negative terminat of the gauge to the "Batt" post of the ignition switch, and
Run the wire from the positive post of the ammeter out to the "Batt" post of the starter solenoid (the one the positive battery cable goes to).

Leave the existing wire that runs between the ignition switch and starter solenoid in place - uncut. (so you actually have 2 wires making this run - the ammeter is wired to one of them).

Reconnect the negative battery cable on the battery.

Should work fine.

The shop manual won't help you with an aftermarket gauge with wire on posts. Ford used induction loop ammeters that the wire just ran through (the wire that connects the starter solenoid and ignition switch)

Good luck

Other way around. Negative side of the gauge toward the ignition switch, positive side of the gauge toward the starter solenoid (and positive battery cable).

Ok, well, that's backwards from all the drawings, but whatever has to be done to get it to work properly is the case. As I said earlier, alot dependes on the individual gauge.

I'm glad you were able to get it in and it is working for you.
