I imagine the old copper core wires may still be available. I watched the guys on Roadkill Garage ruin 2 MSD boxes AND a HEI module in a few hundred mile road trip. Finally realized he had solid core plug wires. The noise did wipe out the MSD in a few hours, I was surprised. They were mounted inside the car too.do they make any that arent these daze?
Solid copper wires will induce a high enough voltage in a parallel plug wire to create a spark in the wrong cylinder. Pre-ignition.I imagine the old copper core wires may still be available.

I don't know what the plug wires are on the old Rambler, with TFI ignition it doesn't matter.
Really good to know! Thanks, knowledge gained.Solid copper wires will induce a high enough voltage in a parallel plug wire to create a spark in the wrong cylinder. Pre-ignition.
We had that happen in one of our engines where we didn't realize the plug wires were solid. Almost lost the engine.
By the same token, any trigger wire that has to run any distance from the distributor to trigger and external module or unit will have a high voltage induced in it and will destroy the trigger circuitry despite the location of the unit.
The TFI module is no exception and may be more vulnerable since it has additional trigger circuitry to control dwell time.
The only saving grace of the TFI module is that it is not a high output device and creates a lot less of an electromagnetic field around the plug wires and the TFI trigger wire would have to be closer to the coil and plug wires to get damaged.
gb500, that's a great question, and I should have addressed it already.Frank- did you keep the condenser on the points - or remove it when you added the tfi module?
Agree. And no change to the factory advance curves played a big role in my decision.I like the idea of keeping the points. If the electric boxes fail you can home on the points!
Just like the wagon my parents had when I was a child. They took the family of six to Florida on a vacation in it once. How we survived is beyond me, but good memories nonetheless...BTW- that's 100% original in there. (Well, until I put that TFI in!) 1959 Rambler, 42,000 actual miles...
standard 1st procedure in the day for more than this 1 M/M/Y.I pulled the distributor out of the engine to get the points and everything else in there set right
Thank you for that input Rod!Just though I drop this link here for the Velleman Ignition Kit, that works on the same principle, using the points as a switch. The nice thing about this kit is that you can set it up for six volt cars, though you may need to fully isolate it for hot ground vehicles.
As an interesting aside, Ford used to offer something similar for their bigger heavy duty engines in the sixties. Their brochures mention them.
