Hi there.
I measure -5v at the sequencer (j2), but the connections to the mainboard is right, and I measure +5v there, when everything is connected.
+15 and -15 is all-right.
What have i done wrong.
Cheers Mikkel

I got the right +5V at the Ride, Crash and Hihat roms, but I have -8V at TP1 and it doesnt react when I turn TM2.

Ok stupid socket at IC118 at leg 1, that fixed the negative current. Now I have 0V at the sequencer section instead of +5V in the sequencer section. I have +5V at the 'instruments' Any suggestions? of where to look?

Check that J2 is in the right way

Missed that it got fed by J2 and I needed to do all the crimping before I could test it.
Everything works now, except the snare.
