    Instead of staying steady at a number it fluctuates greatly. Broken wire inside?

    Or faulty ohmmeter leads?

    You should check that meter on a known good resistor or coil of some kind to be sure.

    Especially digital meters. i have found them flaky.

    Why were you measuring it? Was there already a suspected fault?

    if your ohm meter is working properly, then u may be correct

    I was going to ask if there was an audible issue like weak or scratchy sound...

    First rule in trouble shooting is always to verify the problem and rule out other possible causes along the way.

    This would include cross checking your meter equipment on something else to see if it fluctuates too...

    This can happen in a pickup coil that is broken but still has a capacitive coupling. ....because the meter sends a DC voltage from one probe to the other to take the measurement. Or it can happen on a pickup with a loose connection. That happens on Fender pickups with partial failures at the eyelets.

    Does the pickup sound ok? Sound thin and weak?

    The pickup works. Its pretty bright for a neck pickup. Its as loud as the bridge pup. How do I know if its working to its full potential? Thanks.

    If other similar pickups read fine on the same meter and that one fluctuates strangly, that's a sign in itself that it's not right.

    An LCR meter or oscilloscope could provide more information.

    I think it has a broken coil. How much to fix it, James?
