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.
This can cause fluid to move from the abdomen into the scrotum. Hydroceles can also be caused by inflammation or injury in the scrotum or along the channel. The inflammation may be caused by an infection (epididymitis) or another condition.
