1 > 5 ~ 350 Ω
Step 3: Load Cell Check - cont.
B. Check Excitation Voltage
a. Set your multimeter to measure up to 5V. This is commonly the 20V setting.
b. Place the black probe on terminal 3 (bare wire).
c. Place the red probe on terminal 2 (black wire). The meter should read between
-5.1V and -4.9V.
d. Place the red probe on terminal 4. The meter should read between 4.95V and
5V.
C. Check Static Output
a. Set your multimeter to the millivolt (mV) setting.
b. Check and record the voltage between terminals 1 and 5. A good load cell will
read
very close to 00.0mV at rest with no vehicle loaded.
D. Check Dynamic Output
a. Set your multimeter to millivolt (mV) as with the last test.
b. Place the multimeter pins on terminals 1 and 5 again.
c. Have another person rock the drum back and forth a couple inches (careful not to
pinch fingers) each way while you watch the multimeter display.
d. Record the high and low numbers seen while rocking the drum.
e. Depending on the force applied in rocking, the readout should be ~±.3mV.
Step 4: Grey Cable Check
A. Locate the Grey Cable connecting the red drum board to the black drum coil board. (see
picture below)
B. While watching the input voltage on AIN06, wiggle the wires at each end of the
connector. In addition to watching the voltage on AIN06, also look to see if wiggling the
wires have any effect on the red LED.
C. Unplug the grey cable from each connector and using a multimeter check for continuity
through each wire. To do this set your multimeter to ohms and place one probe on either
end of the wire in question. A good wire will read within a few ohms of 0.
D. With the grey cable still unplugged check to see that each end is pinned the same.
When viewed from behind with the tab up and order should be red-white-black.
E. Plug the grey cable back into each board.
F. If the grey cable checks out proceed to step 5.
