get corroded, you're going to lose performance
that much faster."
With smaller wiring, the effects of corrosion
become exponentially more impactful. One
way to avoid corrosion issues in the wiring is
through proper maintenance and testing methods. Rambeaux suggests eliminating the use of
test lights when diagnosing electrical systems.
"Truck and trailer OEMs
spend millions of dollars to
make all this as weather-tight
and weatherproof as possible,
and the first time a technician
stabs it, all that went out the
window," says Rambeaux,
of using a test light. Instead,
Rambeaux suggests relying
on tools such as multimeters
when diagnosing electrical
wiring. However, more training on electrical systems and
the proper use of multimeters
is paramount.
"Two years ago, our station
at TMC for SuperTech had
100 of the nation's best of
the best [technicians]. Our
average score was only 64
percent," says Rambeaux,
of the multimeter testing
station for the national
technician skills competition station. Rambeaux says
fleets need to invest in training on the electrical systems,
multi-voltage systems, the
tools used to handle maintenance, and regularly
perform proper electrical
system maintenance procedures. "So many fleets don't
do those tests, [stating], 'We
don't have time.' That's not an
option anymore."
Another major consideration from a maintenance
perspective will be maintaining batteries. In a multi-volt
or higher voltage environment, vehicles will most likely be using four 12V batteries
in series. Improper battery
connections may cause significant system issues when
dealing with higher voltages. Technicians must ensure
connection and disconnection sequences are done in
the correct order, as well as
keeping battery packs clean,
to help avoid electrical system
and safety issues.
In order to create an operating environment in
which a vehicle can do its job as efficiently as
possible, innovation and reimagination of vehicle
systems and components will drive changes to the
entire design of the truck and trailer. A reasonable expectation is a truck and trailer combination
with multiple voltages throughout, ranging from
12V to 48V.
Fleets and maintenance personnel must remain
aware of the impending changes on the horizon, as
the introduction of higher and multiple voltages
bring with them implications to maintenance and
component integration practices.
