Question Please?

[Harold in Fla]

I have a coil my friend gave me and the wire was very brittle and i'm going to splice into them and fix the coil but don't know if the coil is worth it, I put an Ohm meter on it and it has four wires, a red, black, yellow and white, well I tested the red and black and got like a 1.7 to 1.9 on the ohm meter and nothing on the other wires is this OK or is it shot, any help would be appreciated thank you.

What detector is it for.

As a general rule VLF have two pairs with low resistance for the RX an TX windings plus a shield which maybe connected to one end of the TX or RX both or neither

Pulse detectors normal have a pair with low resistance for a combined TX and RX winding. Plus a shield which may or may not be connected to one side of the coil.

sometimes red and black wires are 'hot end' related, ie TX. you probably have not RX connection right...
more please on a name of your coil.

[Harold in Fla]

this is an 8" coil named Tornado for the minelab sov.

[kt315]

maybe on RX side there is a preamp inside the coil. cause you do not see the Ohms, but then you have to see kOhms...
that is unprincipially...

Thanks a lot Guru, I tested it again on the higher ohms and was getting reading on all four. thank you Harold

this pic gives you some representation what is sov coil inside, only as an example.

I really appreciate that by getting the picture that helps a lot, thank you. Harold
