i dont want to get near the 31kv when its on, so the upsite i wouldnt do. i will check it tomorow if the cables are long enough for rotating 90° but your suggestion is great! i think i go with yours.

negative i can get from the shielding? the neckboard has a black ground cable that goes the shielding of the mainboard

Probably (without tracing it out). If measuring at CP54, you can simply measure across the capacitor - or at least continuity check between CP54 negative and the shielding first.

2takt:
i got 148.3 v on start up and it goes up to 148,5. this should be good?
