Default 12V power outlet fuse?

Hey guys,

Just noticed my 12v outlets are all dead. Looked in the manual and it shows that Power outlet is #26 (20amp) and the Cigarette lighter is #24 (25amp).

Which one do I need to replace?

Thanks in advance!

Do I have the right slots/fuses?

How do I know which to replace?

You pull it out and look at it. Usually, if it is bad, a very visible gap in the center of the conductor will be visible.

Once you have seen a good one, a bad one is very obvious.

Look at the map of your fuses on the door, pull the fuses with the little white tool (some are yellow) and look at them.

If you pull the wrong one, stick it back in. If it looks good, consider replacing it anyway, unless you have a multimeter to check resistance on it.

The fuses are pretty cheap.

If it blows again, then you need to start troubleshooting to find the problem. Usually a wire with the insulation worn through and touching metal.

changed fuse 24 and 26 and still no sign of life from my 12v outlets.

Any ideas?

Dumb question...what are you using to check the 12v outlets?

Ok, so I figured it out...

The mapping on the fuse box was all wrong...

It showed #24 for the Cigarette and #26 for the Power Outlet.

However, I found the blown fuse in #28??????????????????

I don't get it... Is it normal for this mapping to be off like this?

Thanks!

Perfectly normal. VW is changing fuse/wiring configuration almost every year. I actually checking the wiring 2-3 times everytime I retrofit anything to make sure I am using the wiring applicable to my MY06.

One word: Mess.

Ok, so it burned out again!

The manual states 20amp, but I had nothing to replace it with so I just put in a 25amp fuse.

It seems to be working... Can I do that?

Something that is MANDATORY when figuring these things out is your build date.

I researched 2 build dates in Bentleys and found that through 11/2005 Front and rear lighters are powered by SC 24 (25A) and the trunk outlet is powered by SC 26 (20A).

From 12/2005, all 3 outlets are powered by SC 28 (30A).

There probably is a later build date from about 6/2006 but I didn't see it.

If you have a blown fuse or fuses, a penny or something could be stuck in one of the outlets. Also certain build date cars have to have the key on for the outlets/lighters to work.

Hope that helps....................

If it blows a 20 amp fuse, something is wrong.

What do you have plugged into it?

If the answer is "nothing", then you are risking a fire by installing a larger fuse.

Thats some really good points.

The purpose of a fuse is to protect the wires and to a lesser degree the using devices in the circuit. That is what I was taught about aircraft wiring in tech school, anyway. If a using device is blowing fuses that device is probably toast anyway.

My rule of thumb is if I don't have the correct size fuse, I ALWAYS go lower and NEVER higher. Of course if he has the build that all 3 outlets are on the same fuse, it should be a 30 amp.

Like Dan said, What do you have plugged into it?

With nothing plugged into the outlets, even a 5 amp fuse should not blow..........
