I'm experiencing a strange electrical problem.
The symptoms are:
1) The ignition lock light never goes off.
2) The interior lights are always on. In fact the always on position is now the off position and the other positions are now always on. They have reversed according to the owners manual on page 24 for the coupe.
Has anyone experienced this before?
Is this a malfunctioning relay?
Thanks for any help.

I checked the switches and they are ok. Used an ohm meter.
But, I did notice that the front trunk light does not go out when the switch is switched off. I even disconnected the switch from the circuit and the light remained on. I removed the front trunk bulb to prevent a battery drain (again)
The engine light switch, when manually pressed faithfully turned off the light.

The lights being on means you do have an open circuit somewhere in your car. Use your ohm meter on the door contacts as well. Still that doesn't explain the interior lights/switches being reversed? Have you installed a aftermarket alarm system? Stereo? I had a seven-year-old Alpine alarm system that was failing and was doing similar things. Most notably draining my battery.

My car is bone stock. There is nothing in it that doesn't have a Porsche part number on it.
Open cicuit and reversed lights point me toward a failed relay, I'm thinking or some ground strap has come lose.
Maybe something has worked its way lose over that past years.

Hey Olav,
Had the same prollem about 3 years ago on my 96. Dealer diagnosed as bad control unit for the alarm system. They RNRed the control unit and everything works great now.

Olav, the control unit is under the passenger seat. Mine failed, but the symptoms were different. At almost $300 for a new one, you should troubleshoot all of your switches first. Here is a <a href="http://forums.rennlist.com/cgi-bin/rennforums/ultimatebb.cgi?ubb=get_topic;f=3;t=004554" target="_blank"> thread </a> that you can check out. max

Olav, that is what makes me think it is a light/switch/ground problem, not the control unit under the seat. On a side note; after I paid to get my car fixed and paying large for the control unit, i saw a dismantler advertising used units for $75. If you want to experiment with a different control box, this is a cheaper option. email me for a link if you are interested. max@blue3.net ,max

Max,
I haven't check the integrity of my door switches yet. I'll do that asap.
I'll check the door switches and if they are ok I'll get that link off of you.
Thanks.
