I thought you need several hours of direct sunlight or at least daylight on those units , every day , in order for them to work .. I never thought itd ever work in a garage or carport ..  :o ..  good to know it does ..

I was curious with mine when I noticed the red light coming on with just about any light source. In direct sunlight, it was putting out 1.9-2.1amps. But it was putting out .5 amps in my apartment, with the only light source being my sliding patio door.



AFAIK, .5 amp will overcome any parasitic draw from the alarm, ECU, etc. What it wont do is overcome a dead short somewhere in the wiring.

My car normally sits outside on the driveway, my garage is full of house stuff…. Don’t think a solar cell would really work in a dark garage…! Lol

I drive a '95 968 cab that has a battery drain issue which I suspect may be related to the interior dome light or identical trunk compartment light. Both lights have a 3 position switch, Off, always On, and On that should automatically turn Off in about 20 seconds. Neither light will turn off when switch in in the "delay" position.

My question: What controls the 20 second turn off function of these lights?

The light fixture itself, the trunk or door jam switch or something else?

Any help would be greatly appreciated!

Glove compartment light is a frequent culprit as well

Thanks for the input, but does anyone know what controls the 20 second delay for the dome light to turn off after closing the door when the switch is in the "delay" position?

Think its the central locking ECU that controls the lights delay

Thank you for your response.

Where is the "central locking ECU" located & how would you determine if it is the culprit, other than replacing it?

Thank you,
