Testing Wiring?

you can buy trailer plug testers from most car parts sellers ,they plug into your trailer plug and leds light when the circuit is activated, they some times wont show up a bad earth due to the leds

Hi Angie M,

Most of the caravan service and repair companies can test the car plug with a testing unit - just go down to your local company and I'm sure they'd help.

This link has a great array of pin & socket wiring in Australia

A simple cheap 12v current tester from Dick Smith - earth and in the pin hole should do the trick - get a friend to trip the brakes, blinkers, parking, lights and reverse to test if current is flowing to the correct pins.

Of course - this doesn't guarantee the trailer or caravan has been wired correctly - can only chek that when you plug it in....

Hi Angie M,

You could use a test light and that will tell you if there is power at the plug, get a friend to work the brake , lights, blinkers ect while you test each circuit at the plug and it will show if the plug has been wired correctly and if any circuits are faulty.

If you can connect the alligator clip of the test light to the earth socket of the plug then use the pointy end of the test light for the other sockets it will tell you if the earth return is good as well.

hope this makes sense

Thank you all for such speedy and helpful responses!!

Hi Angie
If you have a multimeter & know how to use it you can check each circuit using this diagram according to your socket configuration.

Don't forget your electric brake wiring!!

You gonna have to get a Brake controller installed if you want caravan brakes.
