2014 Newmar Essex Diesel Pusher 93
IMPORTANT
NEVER replace a fuse with a higher amp capacity fuse than was originally installed. This
compromises the circuit protection by allowing more amperage
to flow through than the circuit was designed for, and could lead to failure of the component being
operated, overheating of the wiring, or fire. Always use the same amperage fuse when replacement
is necessary.
The “dash” fuse panel is located in the left front exterior compartment. This panel contains relays
and fuses that protect Newmar installed dash accessories, including dash lights, blower fan,
auxiliary accessory ports, and more. This panel uses standard “spade” type automotive fuses. The
relays on this circuit board are not replaceable; they are permanently mounted to the circuit board
and should be inspected only by a qualified technician prior to having any work done to them.
Chassis Circuit Protection
The chassis 12 volt DC circuit protection is located in two primary areas on your Essex. First, the
front electrical panel, with fuses and relays, is located in the LF basement compartment, along
with the Newmar dash fuse panel.
This panel consists of fuses and relays that control engine start up and operating functions. It is
recommended that these circuits be serviced ONLY by a trained Spartan chassis technician.
The first basement compartment aft of the right rear tires houses the chassis diagnostic center.
This service area contains diagnostic ports, relays, and circuit protection for the engine and
transmission. This compartment should be serviced ONLY by a trained Spartan chassis
technician.
Batteries
As previously mentioned, your Essex has two different sets of batteries. One set of batteries
operates the Newmar installed “house” lights and accessories, and the other set starts the engine
and operates the “chassis” electrical systems. Though similar in function, they are distinctly
different battery types and arrangements.
Replacement batteries should be the same as was replaced. Any time one battery in a set of
batteries is to be replaced, it is important to have all the batteries in the system tested to assure all
are okay. If one defective battery is replaced, while leaving another weak or defective battery,
lowered performance, or ultimately damaging the new or good batteries can be the result.
IMPORTANT
Charging batteries give off gasses as the fluids inside “boil”. Because of this, it is critical to check the
battery fluid levels regularly, particularly after extended periods of heavy use. Be sure to top off any
battery that is showing signs of depleted fluid levels.
