Rca 21D641 HV issue.

[SwizzyMan]

So I have replaced the filters to start off and that is all the work I have done so far just so I can get a baseline. With no yoke plugged in I pull about maybe 7 kv (I have a shorting bar in the socket so hv will come up.), but when i plug in the yoke and power up the set the hv droops to 100v with brightness at max and 2.8kv with brightness at minimum. I have a bad feeling my yoke may be bad. I ohmed out the yoke and the results were inconclusive. The vertical section reads normal, but when i measure the horizontal winding I get maybe 6.9k wit the target being 29 ohms(provided I am measuring the right pins). Not sure if my yoke may be bad or not. Here is a picture of the yoke from what I gather vertical winding is from pins 1 and 2 and the horizontal is from pins 8 and 4. Your thoughts?
