foglights not working

[Shimian]

Hi all,

A weird thing just happened. Installed a new battery couple weeks back and everything works fine (didn't test foglights then). Then decided to turn on the foggies today and the 20A fuse blew. Put another one in and it also blew. Cannot figure out why. Every other electronic device on the car runs fine such as windows, rear brakes, HIDs etc.
At this stage I haven't had the chance to check the foggies out as I have a mugen kit and have to go from under.
Can anyone give any advice at this point? I can only think of a few things that may have caused the foggies not to work; water got to it, vibration loosened cables, the harness is faulty.

Thanks in advanced

are they OEM type foggies or after market type?

1)
check globes + wire if theyre grounding to the chassis of the foglight housing

2)
trace and check the wiring loom from each foggies back to the relay. look out for punctured wires that could be grounding to the chassis.

3)
If after market, check the positive wires coming from the relay. bascially check all wiries coming into the relay and outgoing. look for punctures etc.

If theyre OEM type and wiring loom, best thing u can do is check for any visible punctures from the fogs to the relay/fuse box.(engine bay fuse/relay box).

good luck

Unless the fogs are getting a direct positive from the battery. the battery change will be unrelated. Do as stated above!

[Shimian]

Thanks for the replies.

The foggies are OEM. Came with my car 6-7 years ago. All I did since was change the bulbs to aftermarket ones. No issues from day one until today. As mentioned, upgraded my battery 2 weeks ago but did not use foggies since.
I haven't looked in the engine bay fuse box but only the interior fuse box and the slot 6 fuse has blown.

bascially check all wiries coming into the relay and outgoing. look for punctures etc. - Not really sure where to find this?

Recheck the globes m8.. Prob fittd them wrong or polarities are other way round...

Theyre H11 55w globes right??

But I haven't touched my foggies since 6 years ago.

Yes they are H11 55w globes.

Haligon globes arn't polarity conscious.

Remove the globes and see if that fixes the fault. If so you have a faulty globe.

If not you will have to trace the cable checking for damage. The short will be melting the insulation around it!

If you cant find the fault. just rewire it. Dont take 5 hours looking over and over again.

You must spread some Reputation around before giving it to JDM DC2R again.

i tried :)

[Shimian]

If I leave them off will they melt the insulation? I am planning on taking it to Honda on my next service to have it checked out.

[JDM DC2R]

No if its off, blown fuse it wont melt, spark, short. As its off!

[Baby Face]

if you plan on taking it to honda why are you asking here?

Well I thought I might get some advise and if its something simple ill give it a go. Otherwise I will take it to Honda but wont be til July.

[Chernoby1]

If i was the honda dealership and you told me of this problem, id try to find where its shorting and then replace the whole wire and if its part of the loom, well the whole loom then. It may prove to be not so cheap :/
If when you look at the place the wire is shorting and you notice its not that big, you might even be able to get away with just taping it up with electrical tape. Sounds like a dodgy fix (and it is) but by far the cheapest and easiest method.

*assumed its a short and nothing to do with the globes (as most globes will become open when they blow).

If it ends up to be the loom faulty then I don't have a choice other than not to fix it. Unfortunately I am not that technical to diagnose it myself. Could there be another fuse in the engine bay that I need to check? I have checked the interior fuse box (number 6) which is for the foglights which continuously blows when I turn it on.

How can it be a other fuse. A fuse is designed to protect the cable after it. So turning on you foglights blows n# 6, why would you think its a other one, especially further up the line?

More then likely Its a loss connection which is shorting at either the switch or globes connection. The cable shouldn't deteriorate on something hardly used. Unless Its been disturbed, damaged or alike.

Since you have no idea. Take it to a auto electrician. And ask for a quote! he may reply cant quote as its fault finding. Then ask for ruff Et and hourly rate and go from there!

It should take him a 1.5hr max to find/ fix the problem . Being 30 mins to search for the fault, If not found start from scratch. Rewiring should take no more then a hour.

cheers JDM. As I mentioned im not technical so im not sure how it all works. Yes I did call an autoelectrician. Told them the case and they said probably around $50-$100 to fix excluding parts if required. Not sure if this is cheap but it seems fair.

[JDM DC2R]

$100 bucks is nothing!

[Shimian]

If it was a harness fault, would this be what I need? http://www.ebay.com.au/itm/HID-Xenon-Relay-Wiring-Harness-H8-H7-H9-H11-5202-9006-/321037085139?pt=AU_Car_Parts_Accessories&hash=item4abf4d29d3 .

If yes, would this be for both foglights or do I need to buy 2?

[Grayfox]

No,

That is for HID units.

If it is the wiring loom.

Go to an auto wrecker and remove one from an old car.

Cheaper than getting on from honda if it is the loom that is at fault.

But i suspect bulb, fuse or relay

[lolmclol]

highly doubt it would be the loom unless you've done something really stupid.


did you actually take the bulbs out after you changed the fuse and tried it again?

[Daveho1]

...............is this thread really happening?
guy;
check the bulbs, if blown replace- problem solved, if not
check the fuse, if blown replace-problem solved if not
check the relay, if blown replace-problem splved if not
check the switch, if faulty replace-problem solved if not
check the wiring, if open replace-problem solved if not

its a pritty straight forward circut, if you dont want to/cant be bothered to learn about electrics take it to an electrician.
personaly i bet one of the plugs is disconected and touching the body/earthing out on the light housing...
