89 560 sel -trouble comes in 3's?
 

Suddenly my oil pressure gauge reads at the max as soon as I turn on the ignition - is this a sender problem and how do I test for it?

The screen on my original equipment Becker radio simply went blankwithout warning,seemingly taking with it the auto aerial function and the dash clock. I checked the fuses under the hood and they appear ok-suggestions please..
I know the radio and aerial are linked but the clock too?

Any and all help greatly appreciated!:confused:

I am no expert, but I would check all the grounds. Faulty grounds can cause weird problems like these. I would make sure the ground strap between the chassis and the engine/trans is not frayed or broken. If there is a faulty ground, electricity will find a ground somewhere else.

Check your voltage with car running. Your regulator might be out, Over about 15.2 volts is NG.

Have you replaced all of your fuses yet?

Thanks for the suggestions, guys - I'll check out grounds/voltage/fuses over the w/end.
