Tip for connectors with crimping pins:
-
use crimping pliers for pins rather than welding,
-
reinforce the output of the wires with adhesive lined heatshrink Tub (more rigid),
-
these "automotive" connectors have a double locking system: when the spindle is fitted, a small click is heard:
first locking. Once all the pins are in place, the second system must be locked:
o
yellow plastic part for male connectors,
o
Lid of the same color for females.
If one of the pins is not in place, it is not possible to close the second lock. If this second locking is not
properly installed, the connector can not be connected.
