where is the most idiot-proof diagram of terminal box wiring?
many wiring diagrams I've seen are apparently some restatement of original diagrams with unhelpful particulars like showing the terminal located vertically, the ammeter is just a circle without plusses or minuses. Other diagrams are apparently from Dykes and show polarity of generator fields. Others reference connections via a plus and minus on the coil, which don't exist on repro script coils. Still other resources go into the alteration made after '28, and some of us are less interested in the "why" than the "how".
One member has pointed out a better diagram in Walt's catalog, but the catalog I have is a diagram rather tiny. References to "driver" or "passenger" side are far easier to comprehend than a "plus" and a "minus" on a coil that don't exist. in conclusion, is there a simple pictorial diagram outside of Shangri-la? |

I thought I read once that the wires can be completely switched over between the two terminal posts and everything was jake but I knew not to go there. |

Here is my rendition of the terminal box wire hookup.

Bob, that is a great diagram. Nice and simple for nice, simple people like me!

Re: where is the most idiot-proof diagram of terminal box wiring?
The diagram shown in posts #2 and #3 needs to be rotated 90° clockwise to put it in perspective.

You rest my case but simultaneously, thanks to the members who took the time to post the diagrams. Perhaps some members have a more innate ease with circuitry. Alas, I'm between the town drunk and the village idiot. yYou |

Re: where is the most idiot-proof diagram of terminal box wiring?
Correct me if I'm wrong, but there is a difference between the 2 diagrams, and it is the Ammeter. Every time I use the diagram in post 2 & 3 I connect my ammeter backwards and it shows a discharge when it's running, so I end up reversing the wires on the ammeter. If you visualize the ammeter as being shown from the rear on this diagram, it will be correct. Since it shows the needle, it appears to me to be viewed from the front, that's where I go wrong.
I like the diagram that Bob posted, it's easy to see how the wires on the ammeter should be connected. Thanks for posting that Bob, I hadn't seen this one before now! |

Re: where is the most idiot-proof diagram of terminal box wiring?
Studying the MAFCA 'wiring seminar' which is correct, page 2 or page 5, diagram for the ammeter wiring ?
Horn wiring page 52 shows the wire terminals installed from the bottom where as I thought the correct installation was into the sides of the horn terminal block ? In both examples, which is correct ? |

Horn from the side.
Ammeter which every way to make it read correctly. many of the repops are backward. (Ive been told) |

Re: where is the most idiot-proof diagram of terminal box wiring?
The two items that are as clear as mud are the coil and the amp meter connection. Many late type amp meters don't even have a + or - indicator stamped on. As was mentioned, if the amp meter shows a discharge when it's know to be charging then just swap the leads. On a coil, a person has to check the polarity. It can be done with a pencil lead but a polarity tester like the one Nu-Rex makes is a bit easier to use. Ford likely had a problem with polarity in the early days of the model A before that service bulletin came out in 1929 to change the coil wires around. It won't run as good if the polarity is off.
