#Ignition wire diagrams manual

Wired back how it was, a stuck or faulty trans control component could still ground the coil. If you get no spark with both of those wires unhooked and then the issue is with the coil or distributor (points). Do the black and green wires switch too? If so, how does this affect anti-stall, kick-down, and other components for the carb and gyromatic?.Is it required to switch the ignition coil wiring to (+) wire to (-) post and (-) wire to (+) post when converted to 12v?.I'd like one that doesn't require an external resistor like the NAPA Part# MPE IC14SB (Thankful for grey beard's suggestion from January 1, 2010) Amazingly so! I need to buy a new ignition coil. That's why I did it this way.Īgain, when the black and green wires were connected as mentioned above, the anti-stall worked perfectly and it shifted way better.

The first three wiring diagrams in the service manual have the same details regarding the ignition coil : (+) to the distributor and (-) to firewall (horn relay?). However, the wiring diagram for the D-42 doesn't show the ignition coil's polarity for some reason (see photo 2).Īlso, regarding the circuit breaker/resistor unit, the black wire is shown in the diagram to connect to the (+) post and green to the (-) post. The Dodge service manual has four different wiring diagrams: The green wire from the circuit breaker/resistor unit was not connected to the ignition coil but just hanging out, not attached to anything.Īnd it did what it was designed to do.didn't stall/die at a stop and shifted way better then before. The black wire from the circuit breaker/resistor unit was connected to the ignition coil's (-) post. According to the late and very knowledgeable Don Coatney's pictures, he wired his ignition coil (-) to distributor and (+) to external resistor/power. Here's the link to his pictures: My car stalled/died at a stop due to the transmission downshift. When I got this car, there were some wiring issues. Issue: No spa rk from 12v ignition coil (with required external resistor in place and properly installed).

If you have a link to a previous post about the issue/questions below, please share. I have a '51 Dodge Coronet (D-42) with gyromatic that's been converted by the previous owner to 12v with one-wire alternator.
