Check the switch connections.
Are J124 and P/J541 connected? Go to Step 4. Connect P/J124
and P/J541.
4 Check continuity between the switch and
the Duplex PWB.
Is there continuity on each wire
between J124 <=> P/J541? Go to Step 5. Repair the wiring.
5 Check for +5 V to the switch.
Is there +5 V across J124-2 <=> ground? Replace the
switch
(page 3-74). Go to Step 6.
6
Check the Duplex PWB connection.
Are P/J540 and P/J417 connected? Go to Step 7. Connect P/J540

1. Disconnect P/J540 and P/J417.
2. Check for continuity at the following:
P/J540-1 <=> P/J417-A1
P/J540-2 <=> P/J417-B1
P/J540-3 <=> P/J417-A2
P/J540-4 <=> P/J417-B2
P/J540-5 <=> P/J417-A3
P/J540-6 <=> P/J417-B3
P/J540-7 <=> P/J417-A4
P/J540-8 <=> P/J417-B4
Are these conductive?
Go to Step 8. Repair the wiring.
8 Check for +5 V to the Duplex PWB.
Is there +5 V across P/J540-1 (+) <=>
