Show flashing

Hi @ all, I would like to have a problem. With a 500 SL R129 Bj.91 the tank indicator, rev indicator, speedometer, oil pressure indicator no longer work. Temperature indicator and clock are fine. If I start the car now a flashing scheme of belt monitoring, battery charge indicator, tank reserve indicator and oil pressure lamp results that it trembles to the nerves. These indicators flash in the approx. 1Hz rhythm so ahead – but should they actually not… Who can give me something s agen and knows possibly also a solution for the problem? Likewise the question, is there somewhere in the net a schematic for above-mentioned vehicle to find? So without it is hard to hang through the wire. Would be nice if someone could help… Here is a MOV file, as it looks like with the link. http://www.file-upload.net/download-8913705/IMG_2674.MOV.html
