Column drop switch what does it control?
On my '41 coupe my column drop switch has some extra wires on it and also some wires that are cut off, I know one of the wires goes to an electric fuel pump with a momentary contact switch in between. I know the ignition circuit is controlled by the drop switch. My concern it that the unknown extras may draw too much current. Car is 6 volt pos ground. Anyone have a wiring diagram or is one listed in a book I should have.

Re: Column drop switch what does it control?
There should only be three wires connected to the ignition switch: Power, Coil & Gauge. Adding extra wires can easily overload the switch. I would connect add-ons to the stud on the CB panel where the power wires from the battery and generator connect. A nice clean installation would be a wire from this CB panel stud to a switch panel and make any additional connections at the switch panel.

Thanks guys, looking at the rest of the under dash wiring I think I should get a new harness.

Re: Column drop switch what does it control?
I notice you live in a cooler part of the world. Try moving to a warmer part and see how long it lasts with continuous use of all that stuff. A 30 to 35-amp system can only handle so much. I do have to agree that the original equipment switches were a much better quality Bakelite type with good quality metal contacts but many folks may have the modern replacements that are not as reliable. This is why I stand by my recommendation. What works for you may do damage for someone else.

Re: Column drop switch what does it control?
That is a wonderful response to those who don't understand watts/volts/amps, etc.
The old stuff was built to lower (read higher) standards than today. Now, if the circuit has to handle 15 amps, design it for 16.5 (10% increase). Back then, it was kinda sorta does it look good. |
