Issue 10:
Speed constantly displays a zero value.
Solutions:
1.
Check speed sensor cable and connectors or the port on the back of the console for loose pins.
2.
Clean pins and sockets on speed sensor cable connectors.
3.
If no speed sensor extension cable is installed, the speed sensor switch assembly may require a
replacement. Contact a local Raven dealer for further assistance.
Issue 11:
(Wheel Drive Speed Sensors) Speed display is inaccurate or unstable.
Solutions:
1.
Check that the issue is encountered on hard surface roads.
a.
If the speed display is accurate on hard surfaces, investigate mounting the speed sensor on a different
wheel.
b.
If the speed display is still inaccurate on hard surfaces, proceed to step 2.
2.
Verify that all magnets are detected by the speed sensor by:
a.
Removing one set of magnets (one red and one black) from the wheel.
b.
Reposition remaining magnets directly across from each other.
c.
Adjust the speed cal by entering a value twice as large as the correct speed cal value.
d.
Recheck speed display on hard surface road.
e.
Continue checking sets of magnets (replacing previously removed set) these two magnets and replace
with other two.
f.
Run speed check again.
If the speed display is inaccurate with only one set of magnets, replace the bad set.
If the speed display is inaccurate with all sets of magnets, replace speed sensor assembly.
Note:
Re-enter original speed cal after testing is complete.
