Note: When you measure continuity to make sure the
MOSFETs are not shorted to ground, you must not have the
screw holding the LT1270A, U4, installed. With no cables
attached, you should read a very high resistance.
LT1270A, U4 Attachment to the heat sink
A 4-40 male/female threaded spacer, 5/16 inch length should
be installed on the heat sink by this time. The LT1270A, U4
part is attached to the spacer by passing a 4-40 x ¼ inch
screw through the tab of the part and screwing into the spacer.
No insulator is required or desired.
