MALFUNCTION
Warning Light Relay Faulty.
CORRECTIVE ACTION
1.
Remove warning light relay from operator station (WP 0155).
2.
Set multimeter to measure ohms.
3.
Touch positive (+) probe of multimeter to terminal 85.
4.

9.
Move positive (+) probe of multimeter to terminal 87.
10.
Keep negative (-) probe of multimeter at terminal 30 of warning light relay.
11.
Multimeter should measure infinite ohms.
a.
If multimeter does not measure zero ohms between terminals 85 and 86, replace warning
light relay (WP 0155).
b.
If multimeter does not measure zero ohms between terminals 30 and 87A, replace warning
light relay (WP 0155).
