Duraspark installation question????????
I have the Duraspark II distributer and the GM module and know how to wire it. I have a few questions though.
1. I have the 86 coil and a Duraspark coil. Can I use either one or do I need to use the Duraspark one. I would think that the 86 should put out a equal or greater spark?
2. The connector to the Duraspark coil is loose. Can it be tweaked or is there a replacement available?
3. With the GM module do I need a resistor in the circuit or run 12 volts?

I am sorry I won't be much help. Just wondering-why? If it is to save money, people gave me several ignition units, and in the end I ended up buying a duraspark at the parts store for $30. My story is that in the end it will be less frustration. Ted

Well I did the Gm module conversion..I used the stock TFI coil..and I didn't put a resistor in..I took teh green cable out of the connector and ran another cable to the the module. it was fairly simple and runs very well got about 3mpg when I did (granted had no timing advance before the swap so it's no surprise)
hopefully that answered 1 & 3 if you use the stock coil i would say you wouldn't need to worry about 2..unles you meant tfi instead of dspark

Ted,
Why? My 86 has a lot of wiring problems and there is evidence that an idiot was under the hood. Lots of splices (twisted and taped) and bare wires skinned back to test I guess. The wires coming out of the TFI (I think it is a TFI) have been taped and soaked in grease. I am replacing the motor and have a Duraspark II which is supposed to be better than the TFI. At the very least it looks like it hasn't been abused. I do not have the Duraspark module or wiring harness so the GM HEI module is the least expensive and easiest way to go. Along with the Ignition change I'm putting on a early model carb. Why? The 86 carb is a piece of garbage and has been rebuilt once. Ford put more BS on this engine than I have ever seen. I just want it to crank and run good.
John,
Sounds good. My 86 coil looks like a transformer with a the Hi-voltage coil terminal looking like a spark plug. Does that sound like a TFI? The wiring couldn't be any simpler especially since I don't need a resistor. Which wire did you use for the 12v feed for the coil?
