here are only 5 serviceable components in the gauge: the
float, the sender bar, the interconnecting fiber optic cable, the
display, and the display AA batteries.
If the float is sunk, the display will read the bottom tank reading
all the time. If the float is partially sunk, the reading may rise and
then fall as the tank is filled. If the float has lost its magnets, the
reading on the display will stay the same as the fluid level changes,
or the reading may appear to stick at one value then suddenly
jump to a much different value.
If the fiber is damaged or the sender bar is dead, the display will
read “no L” on the display. If the light level is poor due to a damaged
or excessively bent fiber, or if the fiber is not fully inserted, or if the
display is not programmed for the same resolution as the sender,
the display will show “bL:xx”, where xx is the number of bits being
received. If the fiber optic cable is disconnected from the display,
a flashing red light should be visible from the end of the fiber.
If the AA batteries are low, the display should flash “batt” every
few seconds. If the batteries are almost dead, the display will be
dim, blank, erratic, or read “no L” or “bL:xx”.
If the display reads erratically, check for water inside the head or
display, and for a poor end cap seal. If no problem can be seen,
the display will require factory servicing.
To test a sender bar:
1.
Make sure the sender is flashing about once a second from
the optical connector. If it is not, the sender is dead and must
be replaced.
2.
If the sender is flashing, plug a piece of fiber into the sender
optical connector and the other end of the fiber into the
OPTICAL INPUT
on the 817 Truck Gauge Programmer. The
top left display shows the number of bits the bar is sending
and the optical power. If the optical power is poor (less than
70), then check the fiber, if it is good and fully inserted then
the bar output is defective and the bar must be replaced.
Ensure that the number of bits is correct (1/3” is 8 bits and
1/6” is 11 bits). If the number of bits is not 8 or 11 then the
bar is defective and must be replaced.
