I have a suspect coil that I need to test to see if it is good or not. It is a NO-24-1400 used for the drop target bank reset in early soild state Ballys. I believe this one is too low, but I cannot find what the proper resistance value is supposed to be anywhere. Every chart on the net I come across has every coil known to man except that one for some reason. Does anyone know what it is supposed to be or can point me to a source that has that info?

this says 10.5 ohms,


[quote] NC-24-1400 , Note that if you can't find your exact coil that you can ignore the letter prefixes as the part that matters is the gauge and the number of turns.

(Note that 5R4 = 5.4 Ohms, as does 5K4 = 5,400 Ohms, values vary due to meter lead resistance) [/quote]

A ha I missed that little footnote. I also found this on the chart.
D24-1400 WILLIAMS FAT 9R4 24 1400 Bank Reset
which is a little different from the other even though the gauge and windings are the same. I suppose it being "FAT" as opposed to "LARGE" may be the difference there. In any case it is vastly different from the 1.8 reading that I am getting which confirms my suspicion that the coil is bad. Thank you very much for clearing that up chas10e!
