" So what now?"

Replace the insulator w/ a square nylon anchor nut. Check out the link below.

" It had battery voltage at the condenser and points connection to the brass screw. Points open or closed, "

Which means you have a dead short, as I said in my continuity check list.

If you do not want to try replacing the insulator, just replace the entire plate for $35 or so. But save the concave head brass screw because the replacement plates do not come w/ them.

"Another question within a question; there's an electronic ignition conversion"

Why? You can fix it w/ the nylon anchor for $1. And quality points correctly installed. EI will not work well at all on 6v (it won't fire below 5.2v) so you would need to convert it to 12v.

EI does not give you higher spark voltage, eliminate all maintenance on your ignition system or give enough of a horsepower boost to cause the tractor to do wheelies. It replaces the points. Thatís it. It will not correct or overcome other problems in the ignition system. While it may give you more HP or improve fuel economy, both would be so insignificant as to be hardly noticeable on a 23 hp engine. If you canít set points or donít care to do it, or you donít want to spend the 30 minutes or so a year to check the gap & lube the cam, then you will be happy w/ EI. And, the EI unit itself will be maintenance free. (but the rest of the ignition system wonít) You will spend probably $235 for an EI kit & 12v conversion. If you install them correctly you will have an easy starting tractor for a long time. And, the 12 volt conversion & EI will have just about nothing to do w/ the good performance. What will make the real difference is the new wiring, cables, clean grounds & new battery.

The key advantage to EI is that you do not need to gap & lube the points every year & replace them every 4 or 5 years or. If you perform annual maintenance on the points & change them every 4 years or so using quality parts, you will see no difference whatsoever between a points ignition system & EI on an N.

The key disadvantages to EI on an N are initial cost, nearly impossible for the average N owner to repair, will not work w/ low battery voltage, & easily damaged beyond repair by polarity reversal & other common mistakes.

Bottom lineÖÖÖ.this is the question you need to answer: ďIf tens of thousands of other Nís operate just fine on 6v and points, why canít mine?Ē

Your money, your tractor, your call........$1 or $240.

Please post back w/ results or other questions.

I had read enough, and had my 8N long enough, to know that I didn"t necessarily need a 12 volt system. I used to have a Ferguson TO-30, converted to 12v before I got it, and didn't notice that it started any easier or ran better than either of the Ns that I've had. And to know that I can fix the breaker plate with just a nylon nut means I can probably get this thing going this week (and I'm cheap enough that I won't spend $35 or $42 or whatever over a buck or two). I've been dinking around with old cars for over 50 years; when I had my first paid for car, it still was put together and kept running with help from local junkyard, so old ignition systems aren't exactly foreign; changing out points and distributor parts will just keep me in practice. And to know I have good help on this site, that much better. Thanks for your help and prompt reply.
