Reels Enable/Disable and Backlap Switches
The reels enable/disable switch is attached to the instru-
ment panel. It is a three position switch that is main-
tained in any of its three positions. Positioning the toggle
back closes the switch between the back (brown wire)
and center (black wire) terminals. Positioning the toggle
forward closes the switch between the front (orange
wire) and center terminals (Fig. 42).
The front and rear backlap switches are attached to the
reel hydraulic manifold block located under the seat
(Fig. 43). When the backlap control valve (MD1 or MD2)
is in the Backlap position, the switch contacts close.
This feature allows only one person to backlap any of the
reels. The backlap switch circuit also prevents reels
from raising during backlapping. When the backlap con-
trol valve (MD1 or MD2) is in the Mow position, the
switch contacts open.
