First Time Predicta Owner

[.Mark Steven]

Needing advice from the experts. I've replaced all caps and resisters on the main board and just waiting on new power resisters to replace the old sand resister that looked ok but obviously toast.
I've checked the power transformer and fly back. Ohms seem reasonable but the vert transformer is funky. SAMS shows 425 ohms between red and blue and 2.5 between the top 2 secondary lines. I'm getting 264 and 3.8 ohms. All board connections are in place. Would that throw off my readings or is my transformer ill? Thankyou for any advice!
Edit- Just pulled the red line off the board and still just 264 ohms.
