Tried removing & refitting the 3 fuses D8,E6 & E8 & then doing the 148 Reset.
One fuse was blown, E6 I think but now replaced.
Alais, still no sound.
the problem started when the battery terminals where for a split second too long on the wrong way.
Likely to be fibre Optics?
Are you saying you connected the battery the wrong way round neg to pos? That can be a very costly mistake. One fuse was blown, E6 I think but now replaced.

Could there be additional inline fuses, can you get a volt meter to the amp connection to see if you have power?

Same thing happened to my 996.
Blew fuse on head unit but also destroyed power amp.
Found replacement amp for around £100. Simple fit.
No other problem.
In light of my CD changer having power & ejecting the CD ok, is it likely to be a replacement amp required.Blew fuse on head unit but also destroyed power amp.

How ?

First of all look up the part number, then try ebay. If you want to go new deal with www.sonnenporscheoemparts.com, I use them a lot and am based in Aus too.If so appreciate a link to a company that will post to Oz..

Reverse polarity connection will pop a fuse on the fuse board, but will also pop the fuse on the back of the PCM unit. Before drastic surgery, check that fuse as well (if you haven't already), you will need to pull the PCM out fully.
It's a 10A fuse on the back of the pcm. From memory it's on the lower right side of the rear aluminium plate of the back of the PCM, if looking straight on at the back face.
D9 will have popped, D8 and E6 should be double checked, although sounds like you have checked all that.

The only test I did was to put my nose near the amp and you could smell straightaway that something had blown.If so appreciate a link to a company that will post to Oz..

Check the model number of the power amp and let me know. I paid around £115 for the one I bought for my 2003 996. If it's the same model I can do you a good deal on it because I've just taken it out and replaced all the stereo with a new component stereo system. The number on my amp is 996.645.331.03

I will get sniffing and report back.Mine is an 05 turbo S, wonder were the amps the same throughout the 911 range.
Maybe PCM 2 's used the same components for all years / models.
If that fails I will have to go looking for the 10 a fuse. Not looking forward to that.
It's quite easy to remove:

You can see the fuse in red on this pic, which is s PCM 2.1, but near enough;

As I said earlier, Im pretty sure you have blown the amp. The amp is not protected against reverse polarity and it will blow the psu. In the 996, opening the bonnet and putting your nose anywhere near the amp location should pick up that smell of electrical component meltdown. Not sure about locations in other 911 models. The amp number 996.645.331.03 fitted straight into my 996 although the original was a 996.645.331.02. Supplier told me the last two digits were a year/version number so were broadly interchangeable. Symptons were the same with power and display to head unit but no sound.
Should be easy to locate a used one locally otherwise let me know.

If component replacement is required, this will provide the part no.s.

All European 996 Ts and North America ones came with bose as standard assume same in aus? It so the amp part no is 996 645 333 07. There are various firmware versions of the bose amp so be careful but as you are a last year vehicle the latest model should be ok.
