Lately I noticed that all the lights inside and outside the car (headlamps, DRL, overhead lights, etc.) are flickering in sync like in the Supernatural TV series. What's going on?
The flickering happens only when the engine is idle, so maybe the alternator is failing? No idea how to check it though.
You are still using the factory lighting.. no weird upgrades??
Hope this all makes sense?
No, everything is stock.
More or less, but it still sounds rather complicated to me, so I'll let the service guys handle it. I've booked a check-up by the end of the next week. Thanks for the info!
Tell us if they flicker..
1. Flicker Differently
2.do NOT flicker
When the engine is OFF : not runnning
So power is purely from 12v engine starter battery.
How fast are the lights flickering and is it a steady pattern or random. A failled diode is likely to give a faster rate than the 25Hz suggested by S130 (depending on design details) but even 25Hz is a pretty fast rate and would not be noticable on a filament lamp (I know this for sure because I've used half wave rectified mains, which gives 25Hz, to "dim" bulbs). If the flckering is random it's likely to be worn or stuck brushes or a bad connection.
Now that video helps a great deal.
That is not flicker (flicker is normally defined as repeated regular higher frequency modulation).
What you have videoed is some form of modulation effect caused by something possibly cutting in and out that is possibly loading and unloading the vehicles 12V system OR the alternator is dropping in and out causing the battery voltage to drop from 14V to 12V and the pack to 14V. A poor electrical joint from the alternator that is heating and cooling could cause this .
Shame you are not located near me (Southampton) as this is an interesting problem that I've never seen before so would have ideally like to investigate with you.
Another thought along the lines of power loading/drain.
Is this light modulation happening after starting and during the engine warm up period?
If so then the 500X has an internal electrical heater in the climate control unit. I don't know the wattage but is does draw significant current. If this is regualting itself by turning on/off then this may be a cause/explanation. Also some 500X models come with heat heaters and steering wheel heater.
So, I drove around with the overhead console lamps on for a while and it seems that the lights "even out" at higher RPM. Has to be related to the alternator, no?
While i think of it is your 500X a diesel or petrol engine?
