Title: Signum rear light fault part 2.
Post by: Field Marshal Dr. Opti on 14 November 2017, 12:50:54
I've removed the rear light unit and found this. With the ignition on I have checked and there is no power getting to the connection 3rd from the left.

All bulbs look intact. Plastic connector looks as though it has melted.

Looked in the handbook but can't find fuse for rear lights.

Fuses on that are all nearside...

Behind left dash end panel, and in left boot cubby :y

The Vectra C has a system whereby if one of the brake lights fails, it ups the current to a side light bulb in order to maintain a brake light on each side... Possible that this has caused the plug connection to melt due to moisture ingress :-\

Might be fog light position on both sides rather than side lights, but either way, check the bulbs for position and wattage along with contact condition ;)

What colour is the wire at the melted contact?

Brake light working rear light is not.I was surprised to find the rear stop/ tail light  work from a single filament

That's the ground/earth/negative*

Check all the bulbs for voltage/wattage and replace any suspicious ones...

*delete for preference  ::)

Canbus varies the voltage to suit :y

Well not actually canbus, the Rear Electrical Centre, when it receives a command for tail lights limits the current through the bulb so it illuminates at a lower wattage, when a brake command is received it allows full current.

In basic terms, the controller has a dimmer function  :y

Shame. I have a shit load of the old style stop/tail twin filament bulbs knocking around. ::)

The main problem appears to be the black plastic multi-connector. The slightest movement and I lose the rear lights.

However, as a  highly qualified engineer ::) I have shoved some bacofoil into the said connector for a tighter fit.

Working as it should (for now) :)

Bodgers were an important part of the furniture trade around High-Wycombe. They turned things like chair legs, spindles etc by hand on simple lathes. Paid by piecework.
