Apologies if a dumb question but clearing the drains in the engine compartment today and noticed a flashing orange light on a plug with a red and a black cable. Located beside the battery. So can anyone tell me what it is and should it be flashing?
Honest I did try search first.

Can you post a Photo?

Right the second black plug is just a blank top to seal the black and orange plug. When I went to the car opened up the bonnet this time the top light of the 3 was flashing bred but within a couple of seconds it had changed to the middle light flashing orange again. Pics below.

Looks like a connector for a trickle charger. Not sure though.

Yes. that is what it is. a trickle charger like ctek. I have the same. it has a dust cover over it. That model apparently has the lights at the connector. the red light blinking might just be to show it is connected and alive.

you can see the connector n dust cover

thanks guys. Had just noticed Ctek on the plug and looked it up. Previous owner must have taken the charger but left the wiring. Worthwhile buying one??

If you let your car sit for a longer time (how long depends on the condition of your battery) it's cerainly worthwile. Mine can sit without charging for at least 1-2 weeks. CTEK is very good, OEM supplier for batterchargers for Bentley, Ferrari and Mercedes. Only difference is the logo and price. Never seen them with lights on the connector. They probably are an indication of the battery condition is my guess.

EDIT:Ehh, forget it... I've searched it for too long others already answered it

Isn't it a Ctek or similar accumulator charger prewire, maybe left there by previous owner? I'm almost sure it is not an OEM thing.

It's a state of battery charge indicator. CTEK charger accessory

Just in case anyone is interested the lights explanation is below. Pity I didn't see the name on the plug before starting the thread.
,Description of Light Sequence,'¢Flashing Green - More than 90% charged and does not require charging.,'¢Flashing Orange - More than 80% charged and should be charged to avoid harmful acid stratification.,'¢Flashing Red - Less than 80% charged,sulphation may be occurring and the vehicle may be in danger of not starting

So time to take it for a run.

 

[Sneaky Pete]

Yes, better do that.
Besides not starting a state of less than 80% charged can, if you read many other posts on the forum, bring all kind of electrical gremlins alive resulting in every weird symptom you can imagine.

...or Float (float charge) as one member would say.

I think we should change it to: "smart" charge :grin:

At any rate, it is always good practice to keep the vehicle battery in its best state/condition to avoid weird behaviour of its electronic components.
