Electrical fun!!

[Si_is200]

Had a few issues over December, firstly be engine light came on but quickly diagnosed it to the o2 sensor had hit something on the road perks of being low!! Then had the rear light warning indicator and oil pressure light come on at the same time plus the rev counter and mpg meter died! really got me baffled as all lights were working and no signs of burning or low oil pressure after full inspection the cause of this issue was a wet fuse box (passenger footwell) a few connection had gone green etc not great! Anyways all lights not out and dried but since this happened the clock will reset to 1:00 everytime be car is started and the Battery is showing the correct voltage, also radio fuses checked and ideas ??

I had a similar issue with my 1st IS200, started off with small bits like yours, my head lights kept coming on randomly when the car off, my dash lit up like a sodding christmas tree and it developed into a massive issue!  I had water is getting into the car and was getting into junction box in the driver footwell.  The water was coming in via the window screen, i am  sure you find thread on here some of me and others with similar issues.  If i remember correctly some people had, had the window screen replaced and it hadn't been sealed properly.  Mine was a original screen and started to leak in the bottom corner on the drivers side.
