Low Voltage

[Stevec0268]

Noticed yesterday that my passenger side rear light was dull compared to driver side.

 

Stripped lights down today and found that I was only geting 6v to the rear bulb whilst I was at it checked front lights and passenger side side light was also only getting 6v.

 

Anyone have any ideas on what could be causing this?

Low voltage would suggest a potential water ingress into the cable or sockets and causing partial short to ground, so it's going to be a tricky one to fix. Obvious ones first, check sockets and where the cables come through the grommets from the interior of car to exterior and check for cable breaks, damage, etc.

 

Also, check it on different days, warm sunny day (lucky at the minute with our weather!) and cold day, see if you get a difference as if its water, corrosion, etc, then the voltage will vary.

Thanks andy,  unfortunately I am back at work today so will have to wait until the weekend when I can check it in daylight.

 

Will let you know what I find.
