Car Indicator Problem

What a fun morning. Roll eyes
I was driving home yesterday and noticed the left indicator was running fast.....a blown bulb.
This morning I dug out a replacement and fitted it......no success.
I checked the voltage at the bulb fitting but as I was using a digital meter and the voltage would be varying between 12 and 0 I couldn't be sure.
I rigged up a test lead and bulb which showed no voltage so the next thing was a fuse.
The problem here is that the fuse panel diagram in the manual bears little relationship to the actual fuse panel.
Fortunately the fuse panel cover has a diagram on it which is much closer to reality.....but has no text, just hieroglyphics.
I quick Google seemed to suggest fuse number 53 which I extracted and tested.....it was ok so I put it back.
Then a last desperate flick of the indicator stalk and the light is now working again. Undecided
All I can surmise is that the fuse had a bad contact and removing and reseating it cleaned it up.
Now comes another puzzle.
The guide suggests that this fuse protects the parking lamps, side lamps, tail lamps (left-hand side).
Problem there is that all the other lights were working fine...and I mean all except that one bulb.
So if that fuse was the problem then all the left side lights shouldn't have worked.
This is going to bug me Angry

Re: Car Indicator

Do I know the answer
Yes / no / Yes / no / Yes / no / Yes / no / Yes / no / Yes / no / maybe / not sure Wink
Sorry couldn't resist Wink
It sure is an unusual predicament to say the least
Is it possible
That a wire / contact / bulb holder going to / from that particular bulb / stalk could be
Loose / dirty / corroded / weak etc
Had a similar thing on an 400 series LDV, where under the steering wheel removable covers, a wire had been chaffing on a metal clip, & worn away part of the outer casing of the wire, cost me £60 to find out after my mechanic replaced the wire, & put some insulation tape of the metal clip, otherwise, it would of cost from LDV an extra £30, just for a bit of rubber to correct their original known fault

Re: Car Indicator

If your car has a can-bus or similar multi-conductor system, it might just have been a bad contact.

Re: Car Indicator

Yes it does have Can-bus.
The fuse might have been a red herring as pulling out the fuse panel could have disturbed other connections including the wire from the left rear indicator back to the panel......I guess I'll never know for sure.
One thing that did occur to me afterwards was to remove that fuse and see what else stopped working if anything.
However:
1) It's a bit of a contortionist act to get the panel out and
2) I don't want to push my luck as I'm going up to Leeds at the weekend

Re: Car Indicator

The other possibility, that springs to mind, yet seems less or least likely
The relay unit, could be on its way out

Re: Car Indicator

Again....why just the one bulb Undecided
Unless it's a 3 pole on/off, one for each bulb on that side.
It was much easier when we had candle lamps front and back.

Re: Car Indicator

It's a mysterious girl one to say the least
& tbh I am intrigued to find the answer
More curiosity (I know what they said in relation to the cat) Wink
Are all the bulbs same make etc
It may be an incompatibility issue ?Huh

Re: Car Indicator

I don't know what make the bulbs are as I bought them from a well known 'bike store' beginning with H.
However the bulb now in and working is the same one I took out as not working so the plot thickens.
I will, at some point in the future, take out that fuse to see the results but not just now.
I also really want to know what the problem was as I don't like mysteries.

Re: Car Indicator

Some things never make sense.
I had a problem with a dashboard radio (and other things) display. It would only work (the other things) if the radio was turned on.
A suggestion was the radio fuse except the radio was working fine.
But sure enough looked in the fuse box at the radio fuse replaced it and the display now works as it should.
And the radio still works of course.

Re: Car Indicator

Probably just disturbing the bulb corrected a minor connectivity fault!

Re: Car Indicator

Ah but where....not around the bulb/bulb holder area, that's for sure....I think.
I checked for signs of life inside the bulb holder and inside the connector Sad
Maybe it's time to raise a fault ticket on my account......clever guys at Plusnet.....or make a 999 call Undecided

Re: Car Indicator

Faulty bulb ?
Normally a bulb either works or it does not but on rare occasions they can play up, make sure you have a spare bulb for the journey.

Unlikely as it's been in for at least a year without problems and is back in and working now.
Actually on reflection I should have taken the opportunity and put in a new one.

Re: Car Indicator

Update:
Apparently it's the bulb holder.
A friendly auto electrician down our road took a look and confirmed it.
It's fairly common with this type of holder he said.
Just need to get one now...around a tenner.
I could get one from a scrap yard but knowing my luck it would have the same problem.
