Rear brake lights

[Jcoz]

Hi all
I have recently purchased a compass magnum 2007
The top brake light works with no issues but I cannot get the bottom two working I was just wondering if anyone had any idea what the issue could be? Bulbs have been checked but can’t find a fuse etc

Probably a corroded terminal(s) somewhere in the circuit.

......fuses for road lights are usually somewhere on the front bulkhead inside the caravan.
Check number of terminals on the bulbs match the light fitment.
It has been known single terminal bulbs to be fitted in a double terminal holder and visa versa.

Ive had a look and bulbs are correct had a look on the fuses for a rear brake fuse and there isn’t one so I will have a look into the wiring to bottom brake lights next, it’s just confusing me as all the other lights indicator etc are working just not the bottom brake lights

Are these fuse "boards" on the back of the front bulkhead, "normally accessed from the side bunks. I have never had problems with my road lights so have never had reason to find any fuses, maybe our van doesn't have any. I must check the wiring diagram.

Front bulkhead (rear of gas locker firewall) some on the right, some on the left of the front cupboard, some are just a simple fuse block , later ones came in a housing with a flip down cover.

If the high level is working the fuse cannot be blown

Jcoz,your other lights are working because you have power to them.Most probably the stop lights haven't a power supply to them and that could well be caused by faults as stated from the posts of forum users ...Good luck... Gary

Just gone through the road lights wiring diagram, and there are NO fuses on my 2013 Coachman, next time at the van I will double check visually. Two lots of terminal blocks though.

That's possible, but it's just as likely that there is no return path (faulty earth). This was very common on rear lights on cars in the days when the light cluster was accessed from under the rear wheel arch. The chassis was used as the return path and the connection to it (from the rear light cluster) corroded. Does anyone know if the chassis is used as the return on caravans? If it is then the connection is likely to be exposed to road spray and moisture. I would expect this to affect the rear lights and indicators as well as the brake lights, but it would depend on how the connections were arranged.

The chassis is not used for negative( earth) return on road lights.
Diagram below of Coachman 2013 road lights.

Mine was manufactured 1992 used 7 core cable included is the earth,(5 core cable including an earth used before 7 core)

 

[toad a caravan]

On some if not most instances the bulb holders were made of pressed steel which was used for the earth,with a spade terminal riveted on to connect to the cable,this sometimes corrodes and causes loss of earth(-v) on all lamp's fitted into the fitting
