If there is no response from any of the following tests, refer
to the main wiring diagram to locate the next connector in
line to ward the con sole and repeat the test at that con nec tor.
If there is a response at that connector, the problem may be
in the cable between the two connectors (or the con nec tors
themselves).
SPEED INPUT
Turn rotary switch to speed po si tion and dis con nect the
speed sensor (yel low tie) from the main harness. Check for
12 volts between pins B (white) and C (black) of the main
harness speed cable (yellow tie). Using a clip lead or other
jumper wire (such as a paper clip bent in a “U”), several times
rap id ly short to geth er pins A (red) and C (black) of the 3-pin
connector
(See Illustration 14).
The console should respond
with some speed read ing.
FLOW INPUT
Turn rotary switch to VOLUME/MINUTE and disconnect the
flow sen sor (green tie) from the main harness. Check for 12
volts be tween pins B (white) and C (black) of the main harness
flow cable (green tie). Using a clip lead or other jumper wire
(pa per clip bent in a “U”), several times rapidly short together
pins A (red) and C (black) of the 3-pin connector. The con sole
should re spond with some flow rate reading.
REMOTE RUN/HOLD INPUT
Disconnect the remote run/hold sensor (or jumper cover)
from the main harness.
Check for 12 volts between pins B (green) and C (violet) of
the main harness remote run/hold cable (grey tie). Placing a
clip lead or other jumper wire (such as a paper clip bent in a
“U”) between pins A (blue) and C (violet) of the main harness
run/hold connector (grey tie) should turn off the “HOLD”
icon on the console display. Removing the jumper should
turn on the “HOLD” icon on the console display.

FLOWMETER
Shaking the Flowmeter end to end should pro duce a “rattling”
sound (shaft end play). Blowing in the meter from either end
should spin the turbine freely. If the turbine spins freely but the
meter will not register flow with a known working sensor, the
turbine may be defective.
See Flow me ter Assembly and clean ing
on page 43 for details.
PLUMBING
Proper plumbing is a very important factor in obtaining
optimal performance from your FlowTrak II system. The chart
on the next page will help you determine what area of the
plumbing may be causing your problem. At this point, it is
assumed that your plumbing basically matches that of the
system diagram and that the flowmeter is installed correctly
and is functioning properly. In addition, make certain that
you have selected and installed the correct spray tips for
the application, speed and spray rate that you intend to
maintain. Don’t forget the obvious such as leaky fittings and
hoses, pinched hoses and plugged or worn nozzles. If you
need more detail than the chart provides,
please refer to
Plumbing Guidelines on pages 36-38.
