Hi all I was wondering about my rear 300zx light badge thingy.

 

It used to light up when the lights were on but has stopped, is it LED and does anyone know what normally goes wrong with it.

These are either a factory option in Japan, or have been made up by a previous owner. Both versions are made up using Electro Luminascent sheets, although the OEM one is of a lot more robust nature.

As for what could be wrong, you'll have to have a look around, as some where there will be an invertor, which changes the 12vdc to 110vac. Now this unit gives off a slight hum when powered. So your first bet is to locate this unit (probably a small black box with four wires coming out of it) switch the lights on and see if it hums, if it doesn't then it could well be this that has gone wrong.

Now for the tricky bit, confirming that it is this invertor. You'll need an electrical metre and check the incoming supply, and the outgoing feed. If you have an incoming supply but no outgoing, then it is defo the invertor, and you should be able to pick one up from Maplin or RS Components.

If you are getting an outgoing feed, then you'll have to move on to the EL Strip situated within the rear centre panel, to check for broken connections and the like in there. If there are no broken connections and you have power upto the EL sheet, then the sheet will need changing.

If you don't have any power coming upto the Invertor, then you'll have to start checking for broken/dissconnected wires within the loom.

Cheers Dave, sounds a bit tricky.

 

The reason I asked if it was LED is I have some kind of heat sink or resister made of ceranic just before the light panel, now this is wrapped in foam, I'm guessing to stop you burning hands, but its not getting hot.

 

I'll look for the inverter unit but I don't remember seeing anything like that when I was trying to get into the panel, all I saw was the resister thingy and then the wires traced back into the loom.

 

Cheers, Scrawn.

That could be the invertor. How big is it?

 

Did the panel light up green?

Sounds like it could be a OEM one then, but I've no idea what the electrics looks like on them, just assumed that they'd be somthing like the aftermarket ones (self-build) But TBH, knowing what Nissan is like, and that they love to charge you a fourtune for nothing, then I'm sure that it would be well over-engineered for what it is!

 

Good luck.

Yes mate the panel lit up, well more blue than green, and its about the size of a relay.

My OEM green panel has an invertor wrapped in foam that is secured to one of the mounting screws that holds the panel on.

 

IIRC there's two wires going in from the loom via a white plug/socket (useful for disconnecting at MOT's) and two that disappear in to the panel.

 

So, probably, 12v DC in and 110v AC out. :)

Is it about the size of a relay on a bracket with a bolt hole in bracket and wraped in black foam if it is its the nissan inverter .Mine went and nissan can not get part numbers for dealer fit jdm options.People have used rs inverters but im confused on which one to buy as somepeople have used rs ones and they have blown after a while or used 2 inverters .Can anyone post the part number of the correct rs inverter to power the factory el panel thanks taff.
