Hello. I am hooking up electronic ignition to my 1970 3000. I have a few questions. 1st the old coil is marked on top battery on one post and distributor on the other post. Is the battery post the positive post? 2nd does this 3000 have a ballast resistor? Any one ever install a Pertronix electronic ignition on a 3cyl ford gas before? Thank you!

The 3000 originally had a resistance wire between the key switch and the coil. It served the same function as a ballast resistor but it did not look like one. There wa a section in the wire between the coil and the key switch that was fatte3r than the rest of the wire and was covered in heat shrink so it almost looked like a fusible link. My '73 4000 had the original resistance wire replaced with a plain wire and a ballast resistor when I bought it and it still works fine.

I would just run a new wire from the key switch to the pertronix coil and call it done.

Small point;
That resistor wire only runs from a bullet connector by the solenoid to the coil.
The rest of it - key sw to bullet connector is normal size 14 - 16? Ga
FWIW, When I put EI on my 3000 ten or twelve years ago I did not know about that resistor wire. I just hooked the red wire on the module to the + side of the coil and the black wire to the - side of the coil.
The EI worked fine even on reduced voltage.

I did the same plus put on a new 40,000 volt Pertronix coil. I don't know but the coil I took off sure looked antique!!! Raining like crazy here (almost 4" in about 24 hours) so I have not been able to get it out and work it. But sitting in the shop it sounds great.

Quoting Removed, click Modern View to seeIt should have had two wires going to one coil small terminal and I want to know where those two go now. By not expecting to know, I meant that by your needing to ask, those Pertronix diagrams, and not knowing what wiring mods may have been made in the last30+ years we may never know.

I traced them both back to the starter relay. I read if you get the Pertronix coil you don't have to worry about the inline resistor. I will call Pertronix to find out. I just know the Pertronix electronic ignition need a full 12 volt to work properly and the old fords only put out 5-9 volts to the old coil and could shorten the life of the electronic ignition. I will test that this morning.

It would be interesting to really know how it is hooked up, but not likely to ever know.

He has a lot to deal with on that 3000, as it had a "in the harness" resistance PLUS the solenoid starting bypass. Fun times!

The coil terminal marked "BATT" simply means it's the terminal to which power is supplied by the ignition switch. It does NOT actually connect directly to the battery.

Since this is a (-) ground tractor, the "BATT" terminal on the coil would be marked (+) if it were not a Ford of that era, and the "DIST" terminal is the (-) terminal, which goes to the distributor points/condenser. Industry standard was to label the terminals (+) and (-), Ford and some Euro stuff was marked as yours is.

If you can accurately measure the primary resistance of the coil, that will tell if it originally used a resistor or not, and you can compare that to pertronix's recommendations as to how to proceed now.

In general terms, if the coil's primary resistance is in the 1.75 Ohm range (give or take a bit), it would have been intended for use with primary resistance in a 12 Volt system.

If in the 3.5 Ohm range, it would NOT have required a primary resistor in a 12 Volt system.

The old coil reads 2.3 ohms

Would seem to be most likely a coil designed for use with primary resistor.

Any idea if your meter is accurate at low Ohms?

What does it read with the test probes shorted together?

It read .6 I have it all hooked up now plus new spark plugs and spark plug wires. Also new rotor and distributor cap and new coil. Guess what? It fired right up and seems to run fine! I will check timing tomorrow.

That photo is the Pertronix instructions. Hope it helps you help me.

Today's Featured Article - Restoration Story: 1964 JD 2010 Dsl - Part 2 - by Jim Nielsen. Despite having to disassemble the majority of my John Deere 2010's diesel engine, I was still hopeful I could leave the engine-complete with crankshaft and camshaft-in the tractor. This would make the whole engine rebuild job much easier-and much less expensive! I soon found however, that the #4 conrod bearing had disintegrated, taking with it chunks of the crankshaft journal.
