TMS700E SERVICE MANUAL ELECTRIC SYSTEM
Troubleshooting Lights
1. Check lamp first. Replace any damaged lamp.
2. If all lamps in a circuit do not work, suspect the fuse and
switch. Replace fuse if necessary.
3. Check the switch and circuit for continuity problems and
other problems. Repair any faulty switch or other
component. Repair wiring if faulty.
Carrier
The following carrier circuit designs apply (Table 3-9)
(connecting wiring and passage through swivel slip ring -- as
applicable -- is understood):
Table 3-9
Superstructure
The following superstructure circuit designs apply (Table 3-
10) (connecting wiring and passage through swivel slip ring -
- as applicable -- is understood):
Table 3-10
Troubleshooting Gauges and Meters
NOTE: When operating from either cab, the gauges and
meters in the other cab will function also. The
gauges share a common sender and therefore
both gauges must be powered, When operating
from the carrier, F5 supplies the power and when
operating from the superstructure, F9 supplies the
power.
1. Check all other gauges and meters (besides the
suspect). If none of them are working, check or replace
F5 (carrier) or F9 (superstructure).
2. Check the gauge or meter, its sensing component, and
circuit for continuity problems and other problems. A
sender is probably at fault when it shows infinite
resistance, or resistance out of specifications for
condition. Repair any faulty gauge, meter or other
component. Repair wiring if faulty.
The following carrier and superstructure circuit designs
(Table 3-11) apply (connecting wiring and passage through
swivel slip ring -- as applicable -- is understood):
