Strange Electrical problem.

Started this morning and im puzzled as to what it could be.

First my sterio stopped working, dosn't power up or anything. Then when I put the ignition on the speedo ODO reading displays and the Trip counter resets, the A/c control unit also resets and turns on the A/c pump. No fuses that I can see have tripped and ive disconnected the battery for 3hours to reset the ECU. Before I did the reset the trip computer didnt clock up the miles but the ODO did, now they both seem to work ok untill you turn the ignition off, then the trip coumputer resets itself and the A/c comes on.

Im puzzled as to what could cause this problem to arrise, the cars fine to drive and everthing else works A.Ok. starting to get worried.

Ive removed the Sterio and noticed that my Hazzard warning light power feed comes off the same feed as the sterio. Is there anyway that this could've effected any of the cars other electrical systems??

Has anyone had anything similar happen to them ??! Any technoheads out there that could help diagnose a problem..... :? :?: :D

Hazard lights shouldn't be connected to the stereo that for sure! 8O So i'd get that sorted whilst your stereo is out! As for the problems I ain't to sure mate! :?

I know my response is a little late but it may help someone else.
There is a circuit that stays powered up when you turn off the key, it keeps power to the trip meter, stereo clock, aircon settings, dash clock.
There is a fuse under the bonnet that directly supplies this circuit. The Hazzard lights are not connected to this circuit.

I had a problem finding this fuse as it wasnt burnt but was cracked. To be sure you need to remove the fuses and put a meter on them.
