Wiring duraspark, need assurance and tips

[66Sprint6]

Im started wiring my duraspark this past weekend and will finish this upcoming weekend. I was wondering, is the diagram from Mustang geezers site exactly how it should be. What I mean is, is the solenoid wires how they should be on the diagram and in the car. The left wire and the right wire. Im doin it exactly like that and dont wanna screw it up. I believe one wire is brown on my car and the other red with a brown stripe. Ive never done this before and would like some assurance. I am following exactly how it is in the diagram, the left wire and the right wire on the front of the solenoid, follow them to the firewall and etc.

"I believe one wire is brown on my car and the other red with a brown stripe. "

I am concerned that you may be looking at the wrong wires. If I recall correctly, these are the wires on the starter solenoid.

The duraspark module gets wired into the duraspark distributor and only requires the connections outlined by Mustang Geezer.

Recheck what you are doing and repost here so we can help you avoid some problems.

I am only working with the two wires off the solenoid that is mounted on the passenger side inside fender near the bettery. If this is wrong, what other solonoid is there??? Im not bein a jackass either, I dont wanna do this wrong, Ive waited too long to get this started and dad wants his truck back, lol, so I MUST do it right. I am using the two wires off the solenoid that if you were lookin at the solonoid from the drivers fender across the motor, they would be facing you. They are the only ones not attached by nuts, the have their own little "L" connections. The other wires to this solenoid are on the right and left of them and face the battery and the firewall. Please tell me I am doin it right, the diagram is vague in regards to which wires.

Matt,

Let me make sure that I am understanding what you want to do. If you are installing the Duraspark Distributor and Module, then you do NOT need to do anything with the wires to the starter solenoid that is mounted on the passenger side fender.

Just relax for a minute, as no one here, especially me, thinks you are being smart about anything. I read your post as coming from someone who wants to do the job right the first time, with no problems.

With that being said, lets review where you should be working.

I am thinking that you are working on a 66 Mustang with a 200 engine. To install the duraspark on this engine, you will need to look at the distributor and coil mounted on the engine. The wires from the duraspark module that you will need to connect are the red and white wires that come from the module.

These two wires will be connected as follows:

The red wire from the duraspark module will be connected to the wire ( I believe it is a red wire) that currently comes from the firewall to your existing distributor.

The white wire can be left disconnected, unless you want to retard the timing a few degrees upon startup. I have left this wire disconnected on my car and have not had any trouble. Make sure that you tape off this connection and wire tie it to prevent it from shorting against something.

Once you have made these connections, the remaining plugs between the duraspark module and duraspark distributor are merely connected to each other.

You should be able to start your car with no problems, provided you have properly installed the duraspark distributor to ensure it is timed properly.

Please let us know how this works out for you.

Kurt.

relax?? Im 45 minutes away from my car and wont get to see it till tomorrow afternoon, Ive spent the past week away from it relaxing, lol. I like the sound of how you say to do it, but check this out, what is the wire goin to the solenoid???? What am I to do about that, here, heres the diagram: http://www.geocities.com/mustang_man_1966/hei.html
Should I disregard this wire? I was trying to be "smart" about it by lookin at the diagram, and I truely meant non of these past posts to sound like Im rushing into this or that I know more than any of you. I ask because I do not know and I want to find out. Now, seriously, should I disregard this wire to the starter solenoid or is that somethin I should continue working on. Thats the only problem with this wiring projectthat I ran into. The diagram says wire it that way and Im checkin to see if thats how it ought to be. Thanx fixastang for the help, what do you think I should do?

Matt,

Thanks for posting the website were you got the drawing from as it clears up a lot. I was looking at the drawing found here:

http://fordsix.com/duraspark.htm

Unless I read it wrong, these are two different drawings. I now can see where your dilemna comes in.

I believe that you can wire it either way. However, based on how well MG's car performs, I would wire it his way. Your primary question is probably which wire to use/cut to make the correct connections.

I am looking at a 66 Mustang wiring diagram and it shows one brown wire and one Red-Blue wire. The red blue wire is the one that you want to cut to do the wiring per MG's diagram. My drawing shows this wire going to the Neutral safety switch on an Automatic car. If you have a stick shift car, you may be able to do a splice using bullet connectors.

If your car is stick, you may be able to look under the dash for the connector that is two red-blue wires together. This would prevent you from having to cut any of the stock wires.

Otherwise, locate the proper wire, cut it and splice the wires according to MG's diagram.

I am sorry for any confusion I may have caused.

Let me know how this works for you.

Goin by that diagram, then lookin at my car, the brown wire is the on on the right and the red/blue wire is on the left if you look at the solenoid like the diagram shows. The red.blue comes first when you look at the solenoid from the front of the car and the brown one is next. I started cutting the brown wire cause that was where it was placed by the diagram, I really need to know if I messed that one up or am I right. Should I have cut the red one to go to the module instead???

I am check a few things out on my car prior to posting any further. I will post a reply with a definitive answer after I get checking a few things out.

Ok here's what you do.

At the + side of the coil remove the red wire. Splice in the red wire from your Dura spark box then hook back up to the coil. Tape off the white wire you don't need it. The green wire from the Dura Spark goes to the - side of the coil. The Purple, Orange and Black go to the Dizzy.

As for the solenoid. The purpose of the I terminal of the solenoid was to provide a good source of twelve volts to the coil when cranking. With the Dura Spark system the white wire used that voltage to retard the timing around 4 degrees which really isn't need with the six.

Trust me it works

I went out to my car to review how I had it wired and determined that it was wired wrong. I rewired it based upon MG's wiring diagram. I did one thing differently after doing some testing.

I turned my key to the run position and checked the voltage at the brown wire on the solenoid. I only have 9.6 volts on it. I turned the key off, disconnected the brown wire, and taped it off to the wiring harness itself.

I next ran a wire from the I terminal on the starter solenoid to the white wire on the duraspark, then connected the red wire with a white stripe from the firewall to the red wire at the coil. I next ran a small jumper wire to the red wire on the duraspark module.

This works great. My car started right up and seems to run well.

I hope your wiring goes well for you. From the sounds of it, you do not need to do anything with the brown wire at all. Just follow the instructions posted by gtm1086 and you should be fine.

The only other suggestion I have is cutting the plug off the duraspark module. The plug on my car switches the red to white and vice versa. I do not know if this will make any difference in how the car runs, but I want it to be correct.

Let us know how things turn out for you.

The I terminal of the starter solenoid will provide 12 volts to the brown wire when it is in the start posistion. The 9.6 volts you are seeing is coming from the +side of the coil with the key in just the on posistion. The brown wire conncts to the red wire of the + side of the coil. so that is why you will see voltage on that wire.

I did not realize that the brown and red wire were connected. I reviewed my wiring diagrams, but they did not show this.

Thanks for clearing this up for me.

I have one other question for you that you may be able to answer. What would happen if the duraspark module was wired backwards ( wires that should go to the red duraspark wire go the white wire and vice versa )?

I am curious as this appears to be the way that my car was wired.

Thanks again for all of your help.

Ok,
So leave the solenoid alone, run the red wire from the duraspark module to the + wire to the coil. The rest is the same as the diagram. Should I leave the wires alone that go to the solenoid, leave them how they were before or get rid of the brown wire??? You guys really are a great help, this will be quite a project for tomorrow, lol.

Matt,

Based on what OTM had to say, I would leave the brown wire alone. I do not think that it will hurt anything to do so.

Thanks for bringing this topic up. I have learned alot by having to review my wiring and hope to have solved some problems of my own.

Keep us posted.

Kurt.

Well, as of this weekend, it is wired. I cut the plugs off the module, but left he one on the disributor and used small connectors to connect each wire. This way if I did it wrong, I can just unplug and see what works and not have to rewire everything. I shoudl be getting my carb back soon and once its on, its startup time!! Will let you know how it goes.
