2N eating points

[Tom N MS]

2N usually runs several years on a set of points but lately it has burnt up 2 sets. Why? Thanks

Have you changed anything like 6/12 volts, coil, ballast resistor, condenser?

 

[Dan]

Bad condensor.

It is original 6 Volt system. Same coil for a long time. Points and condenser changed at the same time just a few weeks ago. Maybe 20 hours on this set of points and condenser that just burnt up.

 

[Tom N MS]

Could have been bad out of the box. Maybe 20 hours on points and condenser that just burnt up.

1. did you lube the rubbing block/cam? points all ways used to come with a little capsule of grease for this, seems they dont anymore.

2. Did you leave the key "ON" for any more than a couple of minutes? Example, just idling while you're off doing something, it stalls, if left for very long the points will burn up if it dies with the points closed.

3. Balast resistor shorted out. Usually when it goes it burns out "open", not closed.

4. New, fresh out of the box, Bad condenser, points to start with. Some times it happens.

Condenser new out of the box bad maybe or the resister on the back of the fire wall has got to the point it doesn't work as it should and causing problem. That resister as your running the tractor changes restance and ifs not doing that any more can cause the point to go bad, not common for it to do that but it can

Thanks.Guess I'll see how this new set does then if they die prematurely I will focus on the resistor.

 

[Tom N MS]

Checking on this for my Dad. I've been meaning to ask him if he lubed the cam on the ones that just dies. I know he did on the ones he just installed yesterday. Thanks

As I said not likely but you never know. Most of the time a resister will just plan burn out but since that one increse resantance as its running and if it doesn't do that then it would cause a problem.

I'm mostly a car wrench but, usually points that burn up prematurly are set either too close or too far out can't remember which it was. Have you considered a eletronic conersion? I belive the parts are avaliable at www.ford8n.com.

 

[Tom N MS]

Considered? Yes, but they are kinda expensive and usually points last a long time.

 

[teddy52food]

Are the points getting oily? How much play in the dist bushings?

 

[Tom N MS]

No oil on them. Bushing was replaced at the time the last set of points(and condenser) were installed.

My guess is incorrect gap, incorrect primary current range.. or bad condensor.

Dufus may have put the wrong resistor in the tractor.Tight point gap will burn points.A coil with shorted primary turns will draw more current. condensers operate at a high AC voltage,around 300 volts, insulation is rated at 700 volts AC.The original condensers were oil filled,this kept moisture out of the condenser.Import condensers are not oil filled and I suspect the makers think that they only need insulation for 6 volts.An oil filled condenser will last for many years.If you have a condenser that is working properly with no burning of points,leave it alone.I test condensers for capacity and leakage.Tests are done at 400 volts.My tractor is running fine on points and condenser that are 15 years old.Just check the gap and clean them.Import points with plastic rubbing blocks wont last long.
