Hi all, this is about a funny phenomenon that occurred recently. Last year in June I bought the van brand new. I made a few trips until December when I took the van to the suppliers for it's first service. When the van was delivered at my home, we discovered that the direction lights do not work while the van was still hitched to the supplier's vehicle. After a short fiddle with the couplings between the vehicle and the van the direction lights were then all working (might have been a lose connection somewhere!!) A few weeks later my subconscious told me to spray both parts of the electrical coupling with Q-20 which made the coupling of the two components much easier. As a test I coupled the electrical connections to test all the lights on the van. I now discovered that the direction lights are all working but all of a sudden the breaking lights are dead. When inspecting my towing vehicle's fuse box, I found that the particular fuse has blown. After disconnecting the electrical coupling between the vehicle and the van I noticed that the breaking lights of the vehicle are still dead. After replacing a blown fuse the vehicle's breaking lights worked again. I am sure that when I am going to connect the electrical couplings, the fuse will again be blown and I have no more spare fuses at the moment. According to my multitester all the points on both parts of the connectors there is no resistance on any of the wires on the caravan side, meaning that the whole diagram should be in order.

Any good advise as how to search for the cause of blown fuses will be appreciated.

if im reading in between the lines correctly, the brake light wire on the caravan has gone to earth somewhere, start by stripping the plug on the van and work through to where the globes go into the holder,  a quick solution is to run a new wire along side the harness from the plug to the globe holders.

two roads diverged in a wood and i took the one less traveled by, and that has made all the difference.

Clean out all the Q20 from the couplers and then test again.

It may well be the Q20 causing the problem.

Flip's suggestion may be right. Q20 on its own will not cause a short, but mixed with fine metal parts from the contact points, creating an electric shortcut to perhaps the ground terminal  is might easily.  In computers the procedure when something goes wrong, is to disable the last piece of equipment or program that you installed and see whether that was the cause of the problem.  the Q20 spray might be this last matter.

First question ............................... when you tested the caravan connection,  did you hook up the caravan to the tow hitch?

As is sometimes happen that the earth wire (white) is not properly earthed on the vehicle side.  Then the lights usually go a bit haywire without a proper earth.

So the earth should be okay on the caravan side as the wires runs directly to the rear lights.  Just make sure of this, then check that the earth wire on the vehicle side is properly ground to the side of the vehicle body or chassis.

If this does not resolve the issue you will have to check each connection from the vehicle female plug all the way to the caravan rear lights. As each connection could be at fault.  I found that on some caravans the little screw of a connecting block was just screwed hard through the little insulation on each wire.  It worked okay in the beginning but after a while it was necessary to clean the wire end properly and reinsert them in the connecting blocks.

I reckon the easiest way to test the van wiring is to use your multimeter and test between all of the terminals on the caravan plug to the earth pin. (Terminal #3) You should not have continuity.

You don't have to strip any plugs, sockets etc.

Sorry! Error!

Take all the globes out as the filaments form a circuit.

Vehicle's fuse blown :  I have had the experience when coupling up without switching all power off.  From there on I switch all lights and the ignition off before I couple the car and van and ever since have not had a problem.

I just want to thank all the guys for there valuable inputs as regards this topic. At the end it looks as if there is no problem with the wiring of the van according to the multimeter test using the earth of the coupling through all points. I now will have to investigate and troubleshoot the female adaptor on the towing vehicle and take it from there.
