Step 3.
Step 4.
Step 5.
Step 6.
Check quick disconnect plugs at electronic control box (u2).
If connections are loose or damaged, reconnect or replace.
If connections are tight, replace electronic control box (u2)
(para. 2-92).
Using a multimeter set at ohms range, check for continuity at points 13 and 14 of
contactor d15.
If no continuity, replace contactor d15 (para. 2-93).
If continuity is present, go to step 5.
With FEEDER ON pushbutton pressed, using a multimeter set to range higher
than 24V dc, check for 24V dc at point 267 and negative ( - ) on terminal strip.
If power is not present, replace feeder coupling magnet (s21) on
electromagnetic clutch (2-88).
If power is present, go to step 6.
Using a multimeter set to ohms range, check for continuity between the points
listed below for each component.
Auxiliary Relay (d13a): Point 81 and Point 82, and Point 71 and Point 72.
Relay (d121): Point 31 and Point 32
Limit Switch (b30a): Point 31 of relay (d121) and Point 143 on terminal strip.
If no continuity is present, replace component (para. 2-93).
If continuity is present, go to step 7.
