Ohm’s Law - Express the relationship between volt (E), amperes (I) in an electrical circuit with resist-
ance (R). It can be expressed as follows: E = IR If any two of the three values are known, the third
value can be calculated by using the above formula.
Purge - The initial blast of air (decompression) from the air dryer purger valve at the beginning of the
air compressor.
Purge Cycle - The time during which the air dryer is undergoing purge and regeneration. This cycle
starts at the beginning of the compressor unload cycle and normally ends well before the beginning
of the compressor load cycle.
Regeneration - The mild backflow of air through the air dryer and out the purge valve that begins
immediately after the purge and lasts normally 10 to 15 seconds. This backflow of air, from the air
system and through the air dryer, removes moisture from the desiccant cartridge and prepares the
air dryer for the next compressor load cycle.
Road Side - This refers to the side of the motorhome which faces the road when it is parked. Often
called the off-door side.
Shore Line - This is the electrical cord which runs from the motorhome to the campground 120 volt
electrical supply.
Shore Line Plug - This is the 120 volt campground outlet that you can plug your motorhome shore line
into.
Stinger - An arm attachment on a tow truck that is used to lift motorhome slightly so that it can be
towed.
Volt - The unit of measure for electric potential.
Watt - The unit for measuring electrical power, i.e., the rate of doing work, in moving electrons by or
against an electric potential.
Wet Cell Battery - A type of battery that uses liquid as an electrolyte. This type of battery requires peri-
odic maintenance such as cleaning the connections and checking the electrolyte level.
