Prior to installing Right Handle/Housing
Halve (27b) onto left housing/handle halve,
be sure that all wires are tucked down in wire
traps. Be sure that wire ribbon is properly
placed down in traps and channels. Make
sure that the PCBA, potted PCBA and
battery terminal block are firmly and squarely
in the corresponding cavities of the left
