MOT failure!

Post by deltic » Mon Mar 19, 2018 10:29 am

Annoyingly, just on an earth fault on the rear lights, I should have spotted it. I cleaned up the earth connections which seemed to do the trick but as I couldn't quite tell whether there was some optical illusion between the indicator and tail light I decide to dismantle the rear light at which point three of the bulbs fell apart! Apart from numberplate lights I don't recall ever replacing any rear bulbs so they must be all at least 17 years old and had obviously deteriorated with age. Something to check.

Re-test tomorrow afternoon.

I had this on mine a few years ago where the taillight was dimming slightly with the indicator on, just earthed direct to the body, problem solved.

Me too. I have soldered in big fat earth cables from the PCBs to the bodywork earth terminal. Annoyingly my MOT tester was keen on checking for the dimming interference from the indicators.
The Joy of BX with just one Citroën to my name now. Will I sing Bye Bye to my GTI or will it be Till death us do part.
