I am having trouble powering my oms drives in the controller. I have the c10, rev 7 bob, c2 mini pwr supply and mh10 oms drives.

Frist I connected the 5v from the c2 to the bob and 5v from the cs to each drive. Measured dc voltage at each connection and get nothing. Disconnected everything and measured volt at the ps and got 5v/12v.

It appears the gnd and 5v have to be connected at each point but the drives do not have a gnd pt for the 5v. The bob has a 5v/gnd pt between each connection (2, 5v/gnd, 3) but I do not get 5v when I measure.

What am I doing missing or doing wrong?
