Key Points of interest are;
If the lugs for Floating Gnd and Scan are
making contact with the Y-SUS board and the
connector P205 or the one between Upper and
lower P204/P110 are removed, the Y-SUS board
will fail.
Floating Ground is delivered to each of the
Y-Drive boards by 2 screw lugs.
Scan is delivered to each of the Y-Drive boards
by 1 screw lugs.
Each of the Y-Drive boards operate from
Floating Ground, (no reference to Chassis Gnd).
Floating Gnd 5V can be measured across C105
(Upper) or C205 (Lower).
