1970 Skylark 350. I ordered a coil from Rock Auto, their description did not include any limitations on the coil. I received it and printed on the coil "use with external resistor". Don't think that will work for my application, correct?
If you have the original resistance wire (pink) still on the car you are ok (assuming you're running points or a unit not requiring full 12 volts).
No points, I just switched to the Lectric Limited kit and wanted to replace the old coil. Where would I find the pink wire?
The "pink" wire is not a resistance wire. The pink is spliced to the resistance wire and taped a few feet back in the harness. The resistance wire has a fiberglass/cloth jacket and is white (or light grey/brown from dirt and oil). But if you have a pink wire at the coil, and original harness, the resistance wire may be visible at the firewall/cowl connector under the brake booster/master cylinder. The wire is 1.80 Ohm.
All you really need to do is read the instructions for the Breakerless SE. I copied and pasted it here for you, If you have any doubts about the coil you bought, I would just use a multimeter across the primary + and - coil terminals, and measure the ohms. If you currently run points, the resistance wire is probably still there.
According to Todd, the Lectric Limited ignition is designed to work with the factory resistor wire and a stock (or replacement style) coil.
Some of you may recall my post this summer where I went thru Buick purgatory trying to track down a stalling issue. The Lectric support guys told me to do 2 things..1) check the ground on the disti as the Lectric unit grounds thru the disti base plate & 2) reinstall the Delco coil vs the replacement. They claim that newer coils create issues as they heat up and fail. I did both... stalling stopped instantly. Which was it?? I don't know but I'm not putting the new coil back... postmortem… it was the new coil causing the issue.
Only kind of wrong. (or partially right) Lol As the guys mentioned the Pink Wire IS tied in with the resistance wire. It's also tied in with the Yellow wire that goes to the "R" terminal on the starter solenoid.
^^^ Yep. The "R" is a relay to provide 12v** from the starter powered circuit to the coil during start. **(actually, full battery current, but folks say 12v because they mean it "overrides" the resistance wire normal operating at 8-9v during cranking)
