Here is the 1950 schematic from http://astrapt.com/wiring/1950-desoto-wiring-diagram.php. Scroll down toward the bottom of the page to see the picture I copied here. Resistor and circuit breaker at top left. Chuck

Interesting that a 1950 wiring diagram has the resistor. Chuck

Thanks! I was concerned about the coil wiring because there does not seem to be a resistor anywhere, and it looks like the coil shorted out and melted wires in the dist. and the harness. I saw a diagram for a later DeSoto that had a circuit breaker and resistor, but there is nothing on this car. I patched up the harness and threw a 12v coil on just to see if I could get a spark and the beast fired right up! The wire that hooks to the anti-stall was connected to the ignition side of the coil, so I need to re-route that to the relay. Someone obviously messed around with this and did not know what they were doing.

Automatic choke and Tip-Toe (?) trans. There are 2 wires going to the carb. One is apparently a switch and I think the other is a "dash pot", although it seems to be called different things in different sections of the manual. All the wiring diagrams I have seen show 2 wires to each item, but I only have one wire to each. The wiring diagram from rb1949 above looks better!

Is there a wiring diagram for the 1947 DeSoto in the download section? I couldn't find anything. I am mostly interested in the ignition wiring section and the wiring to the carb. The diagram that I have doesn't match the car. Thanks, Chuck
