Ammeter Wiring

[Charles Reese]

Ok, admittedly at my advancing age, my eyesight is not what it used to be (and my patience is running a bit thin as well!) Regarding the ammeter … it is my understanding that the driver side post would be considered the ‘negative’ (discharge) post; the passenger side post the ‘positive’ (charge) side.

My first illustration posted below represents, what I believe is the correct wiring diagram … the yellow wire to the driver (-) post; the yellow/black wire to the passenger (+) post.

Somewhere I have scanned/downloaded two other diagrams, which are the genesis of my frustration. I hope they are simply mislabeled and I can delete them into cyberspace. In both of these illustrations the
* yellow wire is shown running to the passenger (+) post
* yellow/black is shown running to the driver (-) post

Since I consider flipping the switch when I enter a room to be an act of personal electrical accomplishment and amazement, and that I don’t want to fry my original early ammeter during that virginal moment when I connect my battery … can someone kindly clarify the ammeter wiring in simple terms (plz don’t just post another diagram!!!) … maybe something insightful like “put the yellow wire on the driver/passenger side post" ...(dont be cute, plz indicate one or the other!!!)
