Angry I cant believe this DOH!!!!

When I was a kid I did the electrical in Tioga Motor homes in Garden Grove ca. . As we all know that our lites are 12 volt. So I decided to redo all my lites in my 5er to Very Bright LED's. They are awesome. The amperage is 0.04 amps. I bought them on Ebay. The roll come with of 600 leds for 16 feet for $20 bux. Now What I don't understand as we all know the red wire is HOT and the black wire is ground. On my 2008 Jayco Eagle 341 RLQS the hot wire is sometimes black for hot and sometimes grey for hot and sometimes for hot blue on my lites on my 5er. How lame is that? Man thank god I used a volt meter so I could make sure what wire was hot and what wire is ground. What a pain in the ass!!! The end result is awesome but not to have a red wire HOT and the black wire is ground was IMHO really lame on the lites not to have RED for HOT and Black for GROUND on a 12 Volt lite system IMHO it's real stupid!!

I agree. Unfortunately they look at an RV more like a house than a vehicle even on the 12 volt side....

Using white for DC ground has been standard in trailers for years and applies to all trailers, not just RVs. The marine industry has also moved away from using black for DC ground because of the likelihood of connecting it to AC hot, also black. You'll find that this also carries over to boat and utility trailers as well. If you start changing the color coding to what you think it should be, you run the risk of causing problems for the next guy who works on it. That's why we have electrical standards.

House wiring is simple. White for neutral, green or bare for ground, black for positive, red for positive in multi-switched or two pole wiring.

Or I think so

It's really not lame at all. Pretty much standard.. White should always be neutral (ground). Whereas black, red, blue, etc. will be the "hot" side of the circuit. The colors are usually just set as circuit identifiers.

1+ for Bob Landry.. He is correct....

What I have found in my HTT is that every wire circuit has a unique color. It makes it really easy to track any OEM wire. Now any circuit I have added are black and white.

Well I guess I'm wrong. I just remember having to wire up a Tioga Motorhome back in the 60's for the 12 volt lites Red was Hot and Black is ground. Well I guess the Times are a Changin lol

just for clarification... Neutral is not ground and should never be considered the same as ground or connected to it. The term ground is used to designate safety ground, is always(or should be) green and carries no current. Neutral is a current carrying wire associated with alternating current. DC ground is also a current carrying wire, but it's associated with direct current and should not be confused with alternating current..

And just to make it easy to understand, the AC neutral and ground wires terminate in the same place. All this simplicity, thanks to Nikola Tesla
