Resistance Check Issue

[btol]

I'm at the resistance check stage and all values test good except the following:

A3 = .664 Mohm
A4 = .600 Mohm
B3 =  .656 Mohm
B4 = .625 Mohm

Manual says they are supposed to read as OL. I've looked over the wiring in those terminals and it looks good to me. Not sure what's going on. Here's pics of each area.

600,000 ohms is sufficiently high not to be concerned.

Yes! Thank you. Hope to be listening to the Moreplay by this evening!
