Default Would you use this coil?

Is this coil good for continued use?

The primary check of the 2 poles shows 2.3k. The specs call for 1.0-1.4.

The secondary shows at 15.5k. The spec shows 5.8k-9.2k.

If you have over 2k on the primary and the spec is for 1-1.4 ohms, then no, replace it.

Try it, not hard to swap in a coil for testing, you may like it.
How accurate is your meter?

Folks forget that a 1.4 ohm coil must use a external ballast resistor then it is fine for a 12V system.


Now note a cheap ohm meter usually is not accurate enough to measure the Ohms correctly.

Yes, especially when you try to measure less than about 5 ohms.

What should the added resister read? I just put a 12 volt battery in my 6 Volt tractor and was planning on buying a coil. maybe I can just make the modification.

Use a 1 1/2 ohm coil rated for at least 30 watts or more. Auto stores should have something in stock.
