CORRECTIVE ACTION
Error Code 1441 - Unswitched Battery Supply
Circuit Failure
1. Check
battery
cable
connections
for
loose
connections and corrosion.
Tighten battery connections and
clean battery terminals as
required.
2. Turn ignition switch to OFF
position and measure battery
voltage from positive (+)
terminal to negative (-)
terminal. Voltage should be at
least 12V for each battery in
system.
If voltage is not as required,
charge or replace battery (WP
0107 00).
3. Turn ignition switch to OFF
position and measure battery
voltage from positive (+)
terminal to negative (-)
terminal. Voltage should be
+12V. Check voltage while
trying to start engine. Voltage
should be at least +6V during
cranking. Check each battery
in the same way.
If voltage is not as required,
charge or replace battery (WP
0107 00).
4. Check circuit breakers 51-F4
and 51-F5.
a. Reset circuit breakers if
tripped.
b. If circuit breakers will not
reset, notify SRA.
+12V = STATIC
+6V = START
