using up ignition points on 8N

[Soundguy]

Forget e-ignition till you are able to care for points.

No such thing as internal resister coil, so not sure what you bought.

A Napa ic14sb is a good coil for 12v. No resistors needed.

Make sure your points gap is correct, too small a gap and they will burn.

Use the correct condenser as well.

Burning points that quick points to a failure in procedure, or incorrect parts, or both.

It's been a while since I've had to deal with points but the way to tell whether it's the coil or condenser is by which side of the points has been arcing or burnt.Sorry I forget which is which .

 

[Soundguy]

NEITHER REALLY IS THE ANSWER.

A 6V COIL ON 12V = OVER CURRENT AND THERMAL DAMAGE TO THE POINTS.

OPEN CONDENSOR = ARC BURNS..

If this was a conversion to 12 volts which is what it appears then an external ballast resistor is likely needed as the coil one is not enough.
These are white ceramic things. You wire them so that when the ignition key is turned to start the resistor is by passed and then in the run position the power to the coil flows through the resistor reducing the voltage and burning up of the points.
Here is a link to show you what they look like.

N don't have key to start ignition switches, they are on and off, and there is a separate button on the trans to run the starter relay, or mechanical switch.

A 52 8n had a 6v coil and no resistor.. Swapping to a 12v coil is a good fix. No extra connections for a resistor, and no guessing the value of the resistor needed. Plus, ok coil could probably use a refresh anyway. Napa ic14sb is a 16$ coil that works fine.. No resistors.


If you don't know anything about the application, you might want to limit your responses to what you know, so that you are helping the issue, not adding to it.

Dave, even with the proper 12V coil you need to run a resistor wire or ballast resistor to feed the coil or the points will burn up in short order.

The points only see a full 12V during the starting circuit as the resistor is bypassed.

To answer the previous question, you will see around 6 V on the positive terminal of the coil while the engine is running, on a 12V system.

Sorry, your answer is 100% incorrect, and is bad info.

Ic14sb coil run with no resistor on 12v.

Go back to school...

There are no starter bypass relay on N!!

Please don't offer advice if you have 0 knowledge of the application!

I don't care about the coil... The points will not last.

 

[Soundguy]

You are just plain wrong.. Sorry.

Finish this tomorrow. Busy tonight
