3.18 BRAKE NOT SET INDICATOR TROUBLESHOOTING GUIDE (CON-
TINUED)
PROBLEM/SYMPTOM SOLUTION(S)
One or two BRAKE NOT SET indicators not flash-
ing when brake is not set.
A. Check for +5 VDC at following boards, connec-
tor J1, pin1:
Gatch/Fowler, right, outer siderail (p/n 3000–409–
913)
Gatch/Fowler, left, outer siderail (p/n 3000–409–
913)
If voltage is present, replace the board where the
indicator is not flashing. If voltage is not present,
check litter CPU board (p/n 3000–300–941) as
outlined in step C on page 63.
B. Check foot board keyboard (p/n 3000–500–
943) for +5 VDC at connector P1, pin 6. If voltage
is present and LED 8 does not flash, replace key-
board (see page 202 for board location).
C. If voltage is not present, check foot board IFC
(p/n 3000–500–955) for +5 VDC at connector P1,
pin 3. If voltage is not present, check for +8 VDC
at connector P3, pin 5. If voltage is present and
problem still exists, replace foot board IFC (see
page 202 for board location).
D. If +8 VDC is not present, check litter CPU
board (p/n 3000–300–941) as outlined in step C on
page 63. Replace, if necessary (see page 115).
