side lights
Hi. just noticed that some marker lights aren't working on my 2013 wiltshire merc
theres 3 side markers on each side,
2 at the top front & 2 at the top rear.
the rear top and 2 side rears are working, but the front top and 2 side fronts aren't working.
i checked the bulbs and they are fine.
so i thought it's a broken wire somewhere, so i tapped into the wiring where i knew it worked and wired it up to a side marker light.
now the one i tapped in to doesn't work and the other sides are flashing occasionly but the majority of the time aren't working either?
i disconnected the link wire and it's still doing it?
any ideas pls? this is baffling me

Re: side lights
The marker lights are powered through the EM50 unit via the vehicle battery, behind the driver's seat? you could remove the relevant fuse in the EM50 or disconnect the VB to reboot the EM50. might work?

Re: side lights
Normally the marker lamps are simply wired through the sidelight circuit ie when you turn on the sidelights the marker lamps also come on. Are the lamps fitted in a fibreglass pod? if so check the earthing is good to the bulb holders.

Re: side lights
they defo go through the EM40 as theres a fuse that says marker lights, no they aren't in a fibreglass pod, there's 2 wires that go to a bulb holder for the side lights which holds a halogen bulb, and the fronts are led'sdavemarshall wrote:Normally the marker lamps are simply wired through the sidelight circuit ie when you turn on the sidelights the marker lamps also come on.

Re: side lights
just spoke to sargent to see if they couls shed some light on it.
they said the rear ones are powered by the EM40 but the ones that ren't working they think are powered by the mercedes side.
i've checked all fuses that i could find with no joy.....

Re: side lights
I no longer have my Merc to check but I think all interface between Merc and chassis is fused on the door side panel on the side of the drivers seat and connections are made under that seat.

Re: side lights
If you read the book linked above it suggests that a relay to control those lights should be under the drivers seat.

found the relay, swapped it for the one beside it, and still didn't workPeter Brown wrote:If you read the book linked above it suggests that a relay to control those lights should be under the drivers seat.
tested the red coming in and that read 13v, tested the yellow/black as thasts the colour of the marker wire and it read 0.03 v so i'd guess the signal wire is a fault somewhere?
am i right? if so where the earth does it get the signal from lol

Re: side lights
Does you van run a Can bus system , this can cause problems if wires are changed as it detects a change and thinks there is a problem

Re: side lights
Have you put back to original wiring and the initial problem, check that all order lamps are working non brighter than the other which indicates an earth fault

From the Body builder link PB posted it seems the lights not working are fed from the MB supply, possible a fuse gone either under diver's seat or one under dash on the passenger side?
