4agze Electrical? woes

Yesterday when I started the adub, I noticed a few warning lights had popped up. The Cooling Fan, Cat converter? and Charge light were all lit up. The supercharger LED is also constantly on. 
 
I disconnected the battery to see if they would clear but haven't. I checked for any codes thrown up but its just giving the constant quick flash which I believe means no codes, right? 
 
The car seems to drive fine although a couple times while trying to engage the supercharger it didn't kick in when it should and I had to let it keep revving until it suddenly clicked in and the car shot forward with a heap of boost.
 
Any ideas? I'm not sure whether to take it to an auto-electrician or not, I'm assuming it's an electrical issue...
 
Cheers.

    Random collection of dash lights is often a sign that the alternator is unhappy.  What's the voltage reading at the battery (ignore the gauge position).

    I've grabbed a multimeter from work so I'll check tonight. I hope it's not the alternator, it got rebuilt about a year ago.

    Just checked the battery voltage and it's only showing 11.8V, I guess that means the alternator isn't charging right?

    If that was your reading at about 3000 rpm then, yep, sorry, alternator is dead.

    Yep didn't go up at all when revving, bugger! Oh well thanks for the help, much appreciated as I'm pretty hopeless when it comes to electrics.

    Just a thought, the alternator belt is still on, isn't it?  Mine once did the same light show, and had spat the belt off when the air/con pump seized.

    Darn - would have been a simple/cheap fix.  At least we don't go through drama's trying to get the alternator out, as our SW cousins do . . .

    Yeah well I was just gonna take it somewhere to get done but after looking at it a but closer I might as well do it myself, seems straight forward enough!

    It is as easy as it looks - just remember to disconnect the battery negative, then the positive, before doing anything else.  Saves fireworks . . .
