Can anyone shed some light on what color wire indicates what? (ie, red="hot", white=Ground/common, etc.)
PLEASE and THANK YOU!
No guarantees that the factory or a previous owner wired according to any known color scheme. That said:
white/black are commonly used for ground. When black is used for ground, red is usually used for positive (typical marine/automotive 12V wiring). When white is used for ground, almost any color - except red - is used for positive (RV cheap). Where it gets confusing is that I have seen some RV 12V wiring with black positive, white for negative/ground.
On 120V AC circuits, the household standard should apply: Black - hot, white - neutral, green - ground. Red is used for multiple switches controlling a single light or accessory (not used in A-frames or PUPs).
The problem is that RVs have both 120V AC and 12V DC circuits. All too often, the dude doing the wiring or preparing a wiring harness doesn't take the time to switch color coding schemes. A meter is the best way to confirm what wires actually do what.
