I am wondering if one of you might have a wiring diagram for the 300SE W112 coupe that you could send a copy of to me. I have a 1967 coupe and we have some electrical issues for whose resolution, a wiring diagram would be most helpful. One issue is a current drain which flattens the battery which is associated with the relay that is normally associated with power operated windows, but the car has manual wind up windows and we don't know what else this relay supplies in those circumstances. The second issue is the power supply to the foot operated windscreen washer pump. My e.mail artlove@bigpond.net.au.

Any assistance gratefully acknowledged.

Art, try the guys on the 3001se.org forum. Surely someone there has a diagram they could email to you.

Peter at Three Point rang me to say he has resolved the battery drain issue. My son had plugged the socket for the interior light time delay switch into the relay and vice versa for the time delay switch after he had reassembled the components on the front of the firewall having refreshed the sound deadener pad! Both items have the same 4 pin plug and are adjacent on the bracket. We presume that we will find the cable for the foot operated windscreen washer tucked up under the dash somewhere.
