Troubleshooting Intermittent Pickup Output Drop
Hi. I recently got a strat where the middle pickup cuts out intermittently. I cleaned and, using a multimeter, tested all the components. As far as I can tell the pickup itself has an internal break somewhere.
After testing the components I wired the middle pickup directly to an output jack. Tapping the top of the pickup caused the output to toggle on and off. I also re-soldered the leads at the pickup eyelets but that didn’t resolve the issue.
Does it seem reasonable that there’s an issue in the pickup itself? The thing that makes me hesitate about the issue being with the pickup is that when I take resistance readings with the pickup removed from the pickguard I always get a reasonable value (~10kohm), but when the pickup is mounted in the pickguard I occasionally get open circuit readings when I do the tap test. Anything else I could/should do to test?
The link below is a short video that shows the pickup intermittently cutting off.

Ran into a similar issue recently with a dimarzio humbucker where it was going dead every now and then. The issue was a broken wire somewhere in the winds, it only worked when the pickup was in a specific position where it bumps into the pickguard (perhaps making the connection due to being pressed in). Same as your case it read at full resistance every now and then depending on how its kept. Ended up replacing it with a newer dimarzio upgrade.
