I was able to locate several wiring diagrams for the Model T, however my 1914 Model T has been altered with a Bosh distributor
& VW coil with 12V system and a volt meter instead of a ammeter .
It also has an electric starter (button) and electric lights (switch).
I would like to wire my brake light so that when the key is off the the brake light will not be on when the parking brake is applied. Any help will be greatly appreciated.
Thank you very much.
Phil, with all due respect, no diagram exists for all the modifications your car has. I would use the stock T electrical diagram, and work backwards on what was removed and replaced to see if you can resolve your problems. One thing i am baffled about is your brake light situation, as the parking brake should have nothing to do with the actual brake pedal itself. Can you post some pics of the setup you have, it would definitely help.
Here is the setup i use, a FP brake light switch right off the brake pedal, problem free since i installed it almost 4 years ago. Hope this helps.
Phil. Does Your car have a 6 volt starter running on 12 volts, hard on the starter system. Does the car have a generator or alternator and is the Magneto still operational and can You switch over and Use it. The brake light problem can be solved by using a horn relay to turn brake light power on and off with the ignition switch, But like John said You need to figure out what,s going on and even a electrical diagram for a 14 won't be much help since they were originally hand cranked and had gas lights.There are a number of different electrical diagrams of the various model Ts with and without brake lights and turn signals on The Texas T web site that I find helpful as a reference. Be nice If Your local club has someone versed in Model T electrical systems to help You.
John Noonan. What is the adjustable bracket next to the neutral cam? It looks to be connected to the emergency brake actuator shaft? The linkage that would allow me to see where it is connected and possibly determine what it does is hidden by springs. Thank you. Jim Patrick
It is an EZ" Adjust Slider, sliding clevis. It allows the parking brake lever to be pulled back with out the brake pedal going down activating the brake light if it is hot wired to system.
Wire the brake light to the same terminal as the coil. When the switch is off there will be no power to it.
Texas T Parts has a diagram (page 5 & 6) that you could use as a guide but may not be the way yours is wired.
What a wonderful forum. Thank you all very much.
Your input is greatly appreciated.
