Pertronix Ignition Quit Again

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I haven't looked into this more yet. But on the electrical system on this tractor nothing is old. Coil has been replaced 3 times. No change. I have no problem with the tractor running on points and it never quits or starts to run bad so I doubt its a coil problem. I'll have to check my grounds again though. Just haven't had time or wanted to mess with it lately. I bought a new alternator but haven't put it on. I've always used 295 plugs. Whats equal to that in a resistor plug? I have suppression wires(brand new from Steve).

	Somebody correct me if I'm wrong but I believe the resistor version is a 303.

	Also it use to have a 3 wire alternator on it. I went back with a one wire alternator when it quit. The new alternator I haven't installed yet is also a one wire.

	The Autolite book calls for the "85" plug for WD45 and D15 II. It's a projected tip resistor plug.

	I've cleaned all connections before but I went over them all again today with the multimeter. They all checked good including distributer and alternator. Coil measured 3.8 ohm. Instructions say 3.0 ohm or more for 4 cylinder. So I guess I'll get those plugs changed and swap out alternators and see what happens. Also may get the matching flame thrower coil?

	That's weird. I've put 10 of these kits in over the last 10 years and have had zero issues. Even been running the 295 plugs.

	As I said, find a Delco CS in the junkyard with the same frame as what you have now. Swapping alternators will be easier that way. Installing a 3-wire would be easier and cheaper. Run it temporarily by touching the "I" wire to the BAT on the alternator once the engine is running. A momentary touch is all you need to start the alternator charging. Even though it's a 3-wire, you only need to use two wires. Don't get a Delco with an "F" terminal, That would be a D model. Most of those have serpentine pulleys anyway.

	I dont understand why it would be easier and cheaper??? I've already been running a one wire on it for years and I've already bought a new one wire alternator. I work 12hr days no junkyard is open when I get home.

	I've been running a single wire on mine for 10 years. That shouldn't be the problem unless a diode went bad, then maybe it's back feeding some frequency and taking the ignition out, certainly a possibility. I'm assuming you have ignition wire going to the plus side of coil and red side to plus side on coil?
