Hi all,
I have an IS200 (1999 Sport) that has always been very reliable but has developed an electrical problem that I will try to describe.
Yesterday when I sat into the car I turned the key and - absolutely nothing. No dashboard lights, none of the instrument needles moved off their stops, not even a click from the starter. There was a high whine coming from somewhere in the car. Apart from that, it was as if the battery had been completely removed or disconnected. I got out with the intention of looking under the bonnet, then I remembered that I had just used the remote central locking to open the door. I clicked the remote again, the indicators flashed, I sat back in and the car started perfectly.
Today my wife called me at work to say that the car was making a funny noise and wouldn't respond to the remote central locking. When I arrived home I sat into the car and once again it was completely "dead". As if the battery had been removed. Except for the red "security" light on the dash and a quiet "beep - beep - beep".
I opened the bonnet and the "beep" sound was coming from the fuse and relay box in front of the battery. I guess it is a relay that sounds the horn when the alarm is activated, but the horn itself was silent. Then I touched the live connector on the battery and suddenly the car came back to life. The horn started sounding. I turned off the alarm using the key remote, and the car started perfectly.
A couple of times in recent weeks while I was driving there was a brief interruption of power that caused the radio to go blank and silent for a second, and caused dashboard lights to come on and in one case, a very brief engine "stutter".
I will be very happy and grateful to hear any ideas of what might be going on.
