Jayco Hawk - Driving lights out of sequence

Thanks Matt, printed the diagram off and will have a look at this tonight - wondering though if they were earth wired incorrectly why do they all work correctly independantly but not together and only go wrong if I have lights turned on on the car. But will check anyway, I am a complete novice as this is my first camper trailer and first time towing anything so this will be a good starting point.

Sharon.

With multiple filament lights, if an earth is loose, corroded or missing, individual lights can find an earth through other lights and become series circuits.
Then once you power the respective series light, you then have the same potential being applied from both sides and no potential difference means no current can flow. Light goes out.

Check the diagrams, Im sure it will be a simple loose grub screw in either the trailer or your vehicle plug wiring.

Oh I see, thanks for explaining that to me. that makes perfect sense now. Will post a follow up tomorrow to let you know how I get on tonight.

Thanks!!

Huh, you should talk, always start a sentence with a capital.

Dont use the Heavy duty 7 pin diagram in that link as its different to what is normally used.

Pin 3 is normally earth as in all the other diagrams
