i take it the header in 7104 and the connector in 7105 go together
it looks like the connector (in 7105) has three wires - white on the right, red in the middle and black on the left
the broken pin seems to be at a position without a wire in the mating connector
it may be that way to stop the connector from being turned around and inserted incorrectly.
what are 7106 and 7107 supposed to show? in 7101 the 1.6 A fuse looks blown
i see fuses, but there is insufficient information to know anything about them
take them out and examine the metal ends - most manufacturers put size, voltage, current etc ratings on the metal
are you plugging the device into the power source it expects?
voltage? frequency?
without more information, you will likely continue to blow fuses.
the fuse is there to protect whatever is upstream from a fault downstream
do you have a schematic or any other documentation?
who is the manufacturer, make, model, part number, serial number of said reel to reel device?
