Ignition Point glazing

[Jonny B]

I got a question from a good friend of mine regarding an interesting issue with a 280 SL:

"Hi, very nicely restored from Germany keeps glazing the points, no spark, has happened 3 times now, replaced points and condenser first time, since then, all have to do is scuff points with file..has proper resistor, did not actually check voltage at distributor..they are not wet, burned, discolored, nothing visual, just lose continuity, like usually happens if sat long time in damp conditions, but this in very short time..ideas??"

Any ideas out there? I did a full search using "glaze" and "Glazing" and got no hits.
Thanks

Are you sure that grease isn't getting on them? Ordinary grease won't work on the rubbing block and it has to be Bosch distributor grease or similar because it will fly off and get on the points.

Do not know, I have sent the comment back to my friend in Ohio.

Make sure his "File" isn't contaminated and transferring foreign material/oil over. Also a bad idea to use regular sandpaper as the glue in it also will contaminate the points.

Sometimes, a no longer functioning factory electronic ignition has been by-passed.  If this is the case, you would also need to change the ballast resistors and coil or else the ignition points will quickly fail. Make sure that the ignition coil, contacts and ballast resistors are matched-up correctly.

Continuing thanks the information has been sent along.
