Hi David.
If you mean from the test points, then I have been doing that. The 5v and 15v read 6¦¸ and 14¦¸ respectively. The 15v rail goes up to 15¦¸ when J1731 is disconnected.
If all the connectors other than J8 (which links A10) are unplugged, then the low ohms readings remain.
I would really like to remove the A10 board and isolate the main A6 board but can't quite see how the face cover comes away from the A2 vertical board?
if anyone knows the trick then please feel free to share the info.
James
