Elkhart Brass SIDEWINDER 8494 ELECTRIC - Manual (Page 5)

Passed; if all testing was within specifications replace the corresponding travel
limit sensor and retest system.
Failed; if all tests were not within specifications move to the connector J04 on
the output pigtail from the monitor control module and retest using a meter
attached to the up/down or left/right motor power terminals. See if placing a
jumper between terminals H and K for left/right or J and K for up/down while
corresponding motor output power is present will terminate power for that
direction and only allow power in the opposite direction. If motor power is not
terminated as described replace the monitor control module. Reconnect
harnesses and sensor and retest to see if travel limits are now working.
10. Find the wire for the function that is not working (left, right, up, down, fog, or
stream) in connector P02. Placing a jumper between that terminal and the ground
terminal in position C should result in the desired output on the terminals for motor
power in connector J04. (Example; monitor won’t go left, a jumper between
terminals in positions G (left) and C (ground) in connector P02 should result in
Positive (+) motor power on terminal D and Negative (-) power on terminal C in
connector J04.)
a) Passed; if the correct motor power outputs are present on the correct
terminals in connector J04 remove jumper and go on to step 11.
b) Failed; if the correct motor power outputs are not present replace the
monitor control module and, reconnect all harnesses, & retest system.
11. Reconnect the harnesses one at a time on the monitor side of the control module
and check for correct motor power at the end terminals when using a jumper
between the same terminals as in step 11. If correct motor power is not present
replace the harness and repeat the test. Keep going until correct power is present at
the appropriate motor power connector (P05, P07, or P09). Leave the meter
connected to the motor power leads and go on to step 12.
