Hi Guys

Hope you are all safe during the lock down.

Are their any specific colour cabling that is used in caravan equipment. Example the lights above the main bed are black and yellow and it looks like feed cable to the light switches is grey and black.

Busy sorting out my lighting problem and pulled the microwave out and chucked out the fridge. And I saw a whole bunch of different coloured wites that come from the Hercules 10 12v connector.

Nee man, jy het dan n 2012 exclusive hoe is dit moontlik dat hy nie standaard bedraad is nie.

Dalk moet ek die classique nagaan... surprised

My van's cable's were standard throughout.

 

I did have a problem that my "Blue Plug" which came standard with the van had the Positive and Negative wires swopped. Also the quality of work inside the plug was 'shoddy/untidy'

Hi Johno,   I will be interested hear if there is any color  codeing for the wiring inside of the caravan, if there is it could become a little confusing.

Of course there is a standard for the wiring  to connect car to van and the tow vehicle, and this will extend to therear lights on the van.

As far as I know the standards which apply generally to A. C. and D.C. should  apply to fittings inside the caravan as well.

A. C...........Brown                         Live

                   Blue                            Neutral

                   Green and Yellow      Earth

D. C............Black                           Negative

                    Red                             Positive

These colors should be standard on all electric wiring unless,  there are two different voltages for DC  ie  12 volt and 6 volt, or 24 volt.

Another area you could find additional color coding could be on real fancy charging and or inverting systems as well as alarm and communication systems.

I look forward to learning more.

Hi Guys

Hope you are all safe during the lock down.

Are their any specific colour cabling that is used in caravan equipment. Example the lights above the main bed are black and yellow and it looks like feed cable to the light switches is grey and black.

Busy sorting out my lighting problem and pulled the microwave out and chucked out the fridge. And I saw a whole bunch of different coloured wites that come from the Hercules 10 12v connector.

I confirm that these are wires inside the caravan not the wiring that is used for the rear lights of the caravan.

Inside the caravan the wire running from the power source are usually a certain color.  Black for negative and maybe grey for positive.  This will go the a switch of some sort.

The black "neg" wire should go all the way to the 12V appliance example a light fitting.  The positive "grey" should go to a switch and from there change color to the appliance like Yellow.

You can easily just test this theory by checking the continuity between the power source and the various points.

The yellow wires indicates that there is a switch between the power source and the light.

Interesting Leon!

I have never thought that the 'Live' colour should change after a switch.

Makes good sense. I wonder if any of our sparky members can confirm and perhaps give the correct colour coding.

This is probably not prescribed color codes but just info I gathered over the years working with it.  The color wire even changed between the Penta of my brother and mine.

That time I installed down ligters in my Penta caravan roof.

I even found that the wires used in a gypsey was different.  The principal stayed the same however.  That is that the color of + wire changed after the switch.

In a Penta caravan left front interior cabinette above the dinette are a few wires.  This is a place where you can pick up a neg and pos wires for an alternative light inside the van.

It is close to the 12V speaker plug mounted in the side panel left front for the light in the Add-A-room.

Hi Leon, 

What you are saying seems to suggest that the wiring actually does not follow any standard, but is generally very random.  If this is the case it would be best to have a Multi meter with you when working on any van. This with at least a basic knowledge of electricity would be the safest way of continuing if you are determined to D. I. Y. or call in someone that has a good electrical knowledge.

Good Luck Johno !

As I said the principle stays basically the same.  The source wires are black(-) and maybe brown(+).  The black runs as the (-) to basically everywhere.  Just the (+) that changes color after the switch.  This can easily be traced using the multi meter as you suggest.

After you confirmed this in the van you have the basics further is easy.

This sort of thing seems to be a trait with some  caravan manufacturers with crazy mass specs, impossible Hitch weights, under rating GWM, random wiring color code ???

One of the few things that seems to be consistent is the color coding for the connecting plug between car and van.

Just some feed back from the weekend. I jacked up the caravan put bokkies underneath and set down the corner supports. Took the wheels off so i could get under the chassis to see whats happening with the wiring. Most of the wires look intact i did find that the shower and bathroom taps wire came loose so retightened them. Didnt work 100% but i think thats the micro switches will have a look at a later stage. Also when i connect the 240v the hercules 10 starting making a buzzing sound and gets louder when i turn any of the lights on... but reading 13.8v so it definitely is charging. Is the buzzing sound maybe coming from the charging of the battery?
lights. I followed the cable for the main light but it doesnt connect to any of the cables that are connected to the main light switch and is also a random colour. so not receiving power i bridged it to the return from another light and seems to be working but will it do anything to system?

Sorry have to add something else. On the hercules db/charger it shows that the 12v input must be on the left of the 8piece connector and its actually currently 2nd to the right. Will it make a difference cause if i remember correctly they are connected on the inside?

So some more digging took place. I have attached 3 pictures of the connector to the hercules unit. Yellow arrow is where the incoming 12 v is and the pink is where is should be. Definitely some thing wrong. I want to move the wires to correct place but i have a problem with it A) Can a person get this connector block any electrical store? B) have any of you been able to remove the cables from the connector bloc? C) if i move the incoming line to where it should be will it still charge? As only one line comes in from the battery straight into the unit. Is there a specific way they are meant to be wired/connected?

i tried contacting lehman transformers but i am not getting answers by phone,FB or email.

Johno, have a look at my thread. Maybe some hints.

 

Perhaps you need to restate your problem. What is not working?

Hi Richard.

i read the thread that is quite a mouthfulšŸ˜ sorry my topic changed from my first post. i hope i make more sense now

I want to put the incoming power from the battery into the correct point in the connector block which goes into the hercules 10. But im not sure how a person can remove the wire or clip without damaging them or the connector block. and if i damage the connector block in picture Does anybody know where i can get them

how do these battery chargers work? Do they use the same incoming line from the battery to charge the battery? 

The main light over the spare bed was connected to a different colour wire that wasnt getting any power(-and the purple wire that it was connected to didnt even have a switch?!)so i coupled it to the other lights just to get it to work. But im worried that i might have stuffed up a connection somewhere thats why i asked if they have specific colours for different functions.

Morning All. 
i finally had a good look at the caravan wiring yesterday. Crawled flat on my back underneath the van following the wires. 
here are the colour wiring for my van:

Grey and black - lights.

yellow and black -down lights by the bed

red and black - goes to a junction then its for the fridge, water pump, gas eletric

blackgrey and black - taps.

Then There is a brown wire that is connected to the power box but isn't connected to anything at the other end. Then purple and another brown with neutral wire not connected to anything at all behind the fridge. It literally started behind the fridge went down did a loop and back up behind the fridge and to nothing again.


I got hold of the guy from Lehmans transformers who helped me quite a bit on where the cables should be going and how i should connect them. So i moved the incoming 12v to the correct place. Its still making a buzzing sound so will ask him what i should do next.
