7. Feed the new cable with connector pins through the
grommet into the reel hub. Without tangling the cable, feed
about 1 ft (0.3 m) of cable through the grommet so as to
provide enough slack to continue.
8. Tie a knot in the cable, approximately 5" (125 mm) from
the end, to secure it from going back through the black
plastic bridge (or the grommet in a 102M Mini reel).
9. For the Mk1 Water Level Meters, by hand, insert the
connector pins into the new Cable Molex Connector. The
negative connector pin is inserted into the terminal on the
pointed side of the Cable Molex Connector, and the positive
pin into the middle terminal (the negative pin is on the lead
with the black insulated braided wire).
11.Position the cable inside the reel hub with black plastic
bridge over top (the notch allowing the cable to run through
the black plastic bridge facing downward) and refasten the
two screws to secure the cable to the reel.
Note: There is no black plastic bridge in a 102M Mini reel.
