Elkhart Brass SIDEWINDER 8494 ELECTRIC - Manual (Page 3)

Problem; monitor will not stop at intended horizontal travel limits.
5. Disconnect horizontal position sensor connectors J08 & P08. In connector P08
check for hall sensor power (+7.5 to 12 VDC) at terminal 3 (red wire), left/right
sensor signal voltage (+4.5 to 7.5 VDC) at terminal 2 (white wire), and ground at
terminal 1 (black wire).
a) Passed; if all values were within specifications. Move on to step 9b.
b) Failed; one or more values did not meet specifications. Move on to step 6.
6. Move to the next connector in the harness towards the monitor control module
and check for hall sensor power (+7.5 to 12 VDC) at terminal position C, left/right
sensor signal voltage (+4.5 to 7.5 VDC) at terminal position H, and ground at
terminal position K. (There may be an extension harness or harnesses between
connectors P4 and J4.)
a) Passed; if all values were within specifications replace monitor harness and
retest system.
b) Failed; if all values were not within specifications;
1. If this connector was on the output pigtail from the monitor
control module then replace the monitor control module, reconnect
harnesses, and go back and repeat step 5.
2. If this connector was on an extension harness move to next
connector in the harness towards the monitor control module and
check for hall sensor power (+7.5 to 12 VDC) at terminal position C,
left/right sensor signal voltage (+4.5 to 7.5 VDC) at terminal position
H, and ground at terminal position K. If all values were not within
specifications move to next connector in the harness towards the
monitor control module and continue testing until you get the correct
values in which case you replace the previous harness extension or
until you reach the control module and still do not get the correct
values in which case you replace the control module. In either case
reconnect harnesses, and go back and repeat step 5.
