348: electrical problem with FUSE / instrumentlights

Does your car's brake light bulbs have dual elements? i.e. are they used for sidelights and brake lights? If so, try removing these bulbs and put another fuse in. If these bulbs are not seated properly or they are shorted, they might cause fuse 10 to blow.

 

So I did take out the #7 out as well as a few harness and still popped.

So when I do put a new fuse in, the front trunk light turns on so does all the lights that pop the fuse with in 2 seconds lol. So i know all the instruments lights do work and are still working but something is causing it to short. Tomorrow i can take out the dimmer little black box hooked into the speedo at the back. I have a few things apart. If you have a wiring diagram to show would be good. I may have to call in a friend to help me.

Weird as it just happened while driving no real reason. I thinking hard and i really appreciate your help

 

I also seen some old posts of you helping others. I wondering if a bad rely would cause this but wouldn't it cause more issues as i seen in other threads.

Would love a 2 min phone chat if that was possible lol.

 

The break light bulbs are 2 single separate bulbs smaller version of a 1156 or 1157 half that size,

 

I would first unplug the connectors from the tail lights and disconnect the inline connector for the license plate lights.

 

Ah, so just a single contact on the bulb base.

@Miro: Does your car have only one lamp on each side of the car for sidelights? That would be contrary to the wiring diagrams.

Looks like I forgot about the licence plate lights. They are spliced to the right hand side inner sidelights in the Euro wiring diagrams.

Sorry, I'm not so good with impromtu conversations. I need to do some research for every answer I give

 

The relay ("B") supplies power to the fuse. It can stop the lights working, but it wouldn't blow the fuse.

By the way, Miroljub has a lot of practical experience with 348 electrics. He often goes the problem straight away. It usually takes me some time to get there

Check those licence plate lights (and wiring). Also, the lampholders are probably quite rusty.

 

So each side of the running rear lights have 2 single bulbs and 1 sing break so 3 bublbs per side 2 of the running lights are out as well just noticed now the picture is the rear right of the car (passanger)

(EDIT)

It looks like yours is different from the Euro lights

According the Euro diagrams, the bulb on the outside should have a different fuse. The two on the inside should be powered by fuse 10.

There is some old threads and some not to long ago do you think i need a Kfuse ?
BOSCH 0 332 015 001 Relay ?

if so any recommendation where to buy one

 

It could be different


the outside light running lights work break lights work but inbetween outside running and break the other running is not working which 100% works with 10 i popped my last fuse trying to see them come on and they do while ignistion is on

 

You may want to invest in a resettable fuse

Your a genius , ill see if any local stores have do you think its the relay now? starting to think the relay is bad and causing straight fuse popping

 

It's definitely not a relay issue. All the relay does is supply power to the fuse when the lights are turned on. If the relay wasn't working, the fuse wouldn't blow.

 

okay that if it was faulty it would blow the fuse... im stuck

 

Stuck until you get new fuses. Did you disconnect the licence plate lights before you blew your last fuse?

 

Lighting issues are sometimes caused by the marker lights on the side of the car.

Look for wiring damage and faulty bulbs/bulb holders. You may have to remove wheel arch liners to get to them. Whether they are on the same fuse, I don't know. Maybe someone has a USA wiring diagram?

 

I see the rear lamp arrangement from this online manual page.

I'm wondering if the side marker lights (I) are linked to the outer rear lights (H) or the inner ones (C).

 

Going to grab more fuses as i cant find resettable fuse unless its on amazon. so for today another box of fuses. Going to pick up some now. Ill try to disconnect the rear plates.

 

Doing this soon sorry i don't know properly how to stay on the same thread and same chat sorry if any confusion.

 

There should be a single connector behind the bumper below the right hand lights

What a team you guys are... honestly thank you guys so much. I bulb was burnt right license plate. I was able to do that first and caught it right away !!!

Thank you both so much greatly appreciate it. Thank for all your amazing help.

 

So you’re saying that the burnt bulb was shorting… now all is ok?

 

Yes that's correct! All done all put back together.

It seems license plates, running back and front lights as well as side bumper lights front and back. Cluster bulbs and gas bulbs all work together on that #10 geeez!
