Dead attys and resistance

[cityboy]

If an atty just doesnt even heat up - is that something that can be fixed? I know there is docs on the forums here, but I searched a few things and couldnt find anything specific. Does anyone know how to test the resistance, and if so, what does that tell you - and does it give you any info on fixing them?

Thanks!

thats something id like to know as well, so heres you a bump

To test the resistance you need a meter.. perferably ne that has a 200 Ohm or 40 Ohm scale. They are relatively inexpensive.

Put one meter probe on the outside ring of the battery connection, and one probe on the center pole of the battery connection. Read the resistance on the meter.

A good Joye 510 atty will read between 2 and 3 Ohms. Typically they are about 2.3-2.5 Ohms.

A good 901 atty will read between 3 and 4 Ohms.

A good L2 510 clone atty will also read in the 3's.

If your atty reads a very high resistance (K Ohms, M Ohms.. or infinite Ohms) then it is "open". And it typically can't be repaired without taking it apart. And that takes some skills.

If it isn't "open", but reads substantially higher than the stock numbers.... it is fixin' to die (go open).

Simple, get a multimeter (volt meter) set it to ohms and touch the red lead to the center of the atty, touch the black lead to the threads of the atty. If there is no ohm resistance then the heating coil has burned out. If the is resistance 2.1-3.8 depending on the atty model then there is a connector problem. You can either do the staple mod or try using a paper clip and cocking the center post by wiggling it left and right and up so it makes contact.
Hope this helps.

Added:
Scott is right, extremly high ohms means the atty is about to die.

Thanks for the info guys, I just dug out an old analog meter I had from years ago. Your info is a big help!

Ahh perfect - answers my question! thank you!
