Greetings, I am working on a 1937 Chevy Sedan I recently acquired and am in the process of cleaning up some of the wiring. The engine is a 235 out of a 61 GM and I believe has electronic ignition. It has been converted to 12 volts (has an alternator) and today I began cleaning up wiring around the starter, coil, etc. and was curious where the wires coming off of the 3 studs on the starer solenoid should go. Currently the wire on the right of the solenoid goes to the Rt terminal on the push button start in the car. The middle terminal has + battery and an ignition + cable running off of it. The left terminal has a wire going up to the left side of the coil which is paired with a wire from the distributor and a wire that goes to the ignition through a ballast on the firewall. I've attached some pics to hopefully help clarify and hope some of you vets can help a novice out. Thanks in advance for any advice and help.
do you know what a wiring schematic is? and how to draw one? It's kind of hard to figure out where the wires go in pictures like that. The S terminal on the starter is what makes the starter turn. The R terminal is the ballast resistor bypass, it should connect to the + terminal on the ignition coil. looks like it might all be connected properly....from what I can see. The two wires from the distributor look like an electronic ignition conversion.
Looks like point ignition to me. The left wire on the solenoid provides unresisted voltage to the coil during crank. This is similar to the resisted voltage in run.
nice schematic. The starter motor has an R instead of an I on it, I hope. There is one more wire, from the coil + terminal to the ignition module in the distributor.
Yes Jim, I equals R. If OP is running electric ignition then the by pass usually isn't used. But !, if ignition switch won't allow for constant voltage to coil during starting the engine the bypass can be used to solve this issue. But since OP is unsure of his ignition and looking at his wiring I'm on the belief it's point's. Need more info or pic of distributor to be more specific.
After a restroom break I recalled there being 3 pictures and I viewed only the starter one. Now that things are more clearer. Can anyone see the problem in this picture ? Is there or Is there not both a + and - connected to the distributor ?
Can you pull your distributor cap off a take a photo please. This will answer the question as to why there would be 2 wires coming from the distributor.
Electronic, the wiring is fine between the coil and distributor providing the polarity is correct. Is there an issue ? Meaning it won't start or run ?
The coil might say external resistor required....looks a lot like one I just installed. But you'd have to move it in the bracket, to make sure.
It has ran in the past, I just wanted to run it by the HAMB and make sure it looked ok. I had a mechanic look it over, but in the past I've found many odd things after a mechanic had "looked it over".... Anyway, the wire off the coil goes into a ballast resistor (I replaced the old rusty one) and then into the firewall/cab. Sound accurate?
Yes. The wire going into the cab is connected to your ignition switch. This is where the 12 volt power comes from to run the ignition.
^^^^^ Your color's may vary but this is the whole of it. Exception being the second distributor wire that you have because of the conversion.
Thanks for the picture, that's a big help. One question, my ignition only has two screws coming off of it (see pic) Will that change anything?
Zac here's your set up (low picture) per your #18 posting. Please note, you have a push button start switch that's in that photo as well.
