NOTE
The DDEC system, tachograph, 24 volt alternator, and turn signal
flasher draw on batteries even when the vehicle is shut off. It is
possible for these accessories to discharge batteries if the vehicle
is not operated for extended periods.
Step 1.
Check if TRAILER LIGHTING and WIPER circuit breakers have
been tripped.
Reset circuit beakers that have been tripped.
Step 2.
Check all four batteries, terminals, cables, and posts for looseness,
corrosion, or damage.
Notify unit maintenance if faults are found.
Step 3.
Check fluid level of each cell on all four batteries. Fluid should be
1/8 in. (3.2 mm) below split ring.
Fill cell(s) with distilled water if fluid level is low.
