Decent auto electrician in Sydney?

I've been having battery drain problems, and initially I replaced the FSU which was failing (Fan blowing at variable speeds after car was turned off, etc) and this appeared to fix the problem. Yesterday, the alarm went off at 7.30am, endearing me to the other residents of my unit block. I called NRMA and after hooking 2 batteries together they were able to get the Beast to crank over. I've searched the forums and have taken the Sat Nav DVD out of the Nav Unit in the boot in case this is what's causing the drain (apparently they sometimes spool up of their own volition, "waking" the car up and draining power). I've also noticed that the word "DSP" sometimes blanks out in my Nav screen before returning to full functionality. It appears to me that maybe the DSP or the Nav is causing the power drain issue, but I need to take the Beast to an auto electrician to determine the exact cause. Does anyone have any suggestions; the "stealer" on the LNS has treated me like an ignorant gumby, and consequently will not be getting my business.

Any suggestions gratefully received, as I want to trust my Beast, but currently don't .......

Since the last post, I've managed to stop the battery drain by removing fuse 56, and stopping the Nav from constantly running (despite the car being turned off). The DVD was on when I opened the boot (red light on), and this apparently can drain at about 2 Amps (?), and not allow the car to go into sleep mode.

Many thanks to all the posters over the years whose in depth explanations allowed me to slowly isolate the problem. Next, to find an auto electrician in Sydney who can help me stop the Nav from constantly drawing power. Than I'll be able to trust the Beast once more.

This board rocks, the amount of experience is sensational!! Thanks to whoever initiated it; was that you Gustav?
