The electrical system in your RV can seem complex and confusing until you have a basic understanding of how it works. Your RV actually has three separate electrical systems. It has a 12-volt DC automotive system, a 12-volt DC coach system, and a 120 volt AC coach system.
Usually, the only indication of a hydrocele is a painless swelling of one or both testicles. Adult men with a hydrocele might experience discomfort from the heaviness of a swollen scrotum. Pain generally increases with the size of the inflammation. Sometimes, the swollen area might be smaller in the morning and larger later in the day.
A hydrocele is a scrotal collection of clear fluid (hydro = water) in a thin walled sack (cele = swelling) that also contains the testicle. Less frequently, due to the common embryological background of male and female gonadal structures, female children or women may also experience a hydrocele.
