dead coil question

Say you have a 16k pup with one dead coil. With red and white together and the probes on black and green, what will the reading be? 16k, 8, 0?
 
Re: dead coil question

Reading from main hot and main ground, you should get the dread "0L", which means infinite resistance.

Hmm. I'm getting the "OL" with probes on the green and white. 8.61k on green and red. Then 17.13k with red and white together and the probes on black and green.

How can I be getting the 17.13k if one of the coils reads "OL"? Weird.
 
Re: dead coil question

That's because green and red are the beginning and end of one of the coils, black and white the beginning and end of the other coil. By connecting red and white together, you measure across black and green and get the total of both. What do you get when measuring across black and white?

Black and white= 8.46! Nice! Ya learn something new every day!

I sold a dime yesterday. Checked it on the multimeter before the sale and it read around 17k. Guy calls me later and says the tech cant get it to work in the #4 position (no sound and hum) , but it works in #5. Didnt make sense.

If one coil goes down, the pup wouldn't work in series. You'd get silence or at best an 8.5k single right?

Wanted to check each coil anyway. Gave him his money back. Figure it was the switch (or the tech) that was the problem.

I'm psyched the pup wasnt broken before or after the sale.

Thanks guys!

Re: dead coil question

By grounding the red/white together with a toggle switch, that shuts off one coil and you guessed right, you'd get at least an 8.5k single or somewhere around there depending on what each coil measures. That's "splitting" the pickup. With red/white together and not grounded, you've got both coils for the full blown humbucker sound.

Sounds like the tech was the problem. ;)

The green and white wires are not from the same coil so when the red and white wires aren't connected, it would be weird if you DIDN'T get "0L". Try black and white and you should get something like 8.6k there too.

Anyway, if you're getting 17.13k, it sounds like both coils are fine.
