Bendix Scintilla coil

[Ronald Smith]

Was able to obtain a replacement coil for my Champion Blue Ribbon 1J project. Of course the replacement coil is configured differently than the original. Original had a wire out each end and the replacement has both wires out one end.

Being new to all this, my working theory is that the 2 wires, one black and one red, constitute the primary; and the sparkplug connection ring is one side of the secondary.

My question is how to test it. I have two meters both only have a 2K ohm setting, no 1K.  I get that I connect black to black and red to red across the primary to test it. How do I connect to test the secondary? Also, I can find no reference for expected values for this Bendix Scintilla coil.

I get numbers on the primary, bit nothing on the secondary.

Sorry, picture files are too large to send

To test the secondary, meter across the high tension terminal and either of the primary wires.  But if your meter only goes up to 2K ohms, you may not get a reading.  Never heard of one like that.

Tom,

Sorry for the confusion.  My meter has a full range of settings.  It just doesn’t have a 1K setting. See picture.

Tom,

Set for 20K and got a reading of 3.8 on the secondary.

Thanks for stearing me in the right direction. Onward to getting spark. Thanks again. AOMCI is awesome.

Black is probably a common ground for both circuits and red to the points.

Mumbles. Thanks. Sounds right.
