Not enough cable tension.
Lower spring tension bar. The lever and
pawl must be pulled downward while the
ratchet pulley is prevented from rotating.
Approximately 2-4 more clicks are required
from this position; then raise spring
tension bar and re-examine results.
Caution : The MRM may inadvertantly
cause system discharge if left in this
position.
Proper Cable Tension.
Correct
Detection Cable tension is obtained when
the bottom edge of the linkage bar is
aligned within the gray "pie" region of the
indicator label, with the spring tension bar
in the "up" position. Stand directly in front
of the MRM while viewing. The lower edge
of the linkage bar will essentially be
horizontal.
Too Much Cable Tension.
Lower spring tension bar and unhook the
blue spring from the tension bar, releasing
all tension. Repeat the process until
Figure B is achieved.
Caution
: damage
to the MRM can result from careless
over-tensioning of the assembly.
