Trailer wiring loom earth

[Ty Korrigan]

So, I have an electrical issue which gives me half of my chipper lights.

On the truck, specifically a 2007 Iveco, where is the wiring loom earth to be found?

On top of the battery is a plate with multiple connections.

Could it be here?

Might as well try the basics before I call in an auto-electrician.

Sounds more like a trailer fault than a vehicle fault.

 

If all of one side of the trailer does not work sounds like a cut cable or the earth in the light unit is faulty.

 

The brake lights are combined so if one works so should the other.

Do you have a digital volt meter?

Chipper lights work fine on other vehicules though and there is a dash board yellow warning light permanently on merdre alors...

I have mixed feelings about those.

 

I use one during a group fleet towing course to diagnose why one of their vehicles did not make the lights on a trailer work.

 

It tested the trailer as fine & the vehicle as fine.

 

When I looked closer the vehicles rear lights did not work at all. The main loom had been cut to the rear of the vehicle. The tester applied current to the socket, through the cars bulb to earth and found a circuit so declared it ok.
