Help with a B&K 1077PAL

Yeah I suspect they are the same yoke. Even the values of the R/C in the sweep circuits are the same between the two.

That said, getting my hands on one of those is going to be complicated; I would really like to try to figure out the one I have.

I spent another hour poring over this thing with a magnifying glass last night, millimeter by millimeter, and I can't see anything broken. But those wires are quite thick and heavy. It seems unlikely one would just open up on it own. And that brings me to the tests I did with an ohmmeter. The other coil measures 32 ohms, which seems about right. This one doesn't measure open; it measures 1.5M. And I noticed last night that if I leave the ohmmeter connected, this happens:



Why does this measure 1.7M instead of open? And why, if it's open, does it increase in resistance (repeated with two different meters)? And if it's not open, why does it measure so high?

Anyone?
