[RICHR]

i HAVE A 560 SL 86
electrical I have a problem with neither battery or alternator .I start the car with a new charge on the batterty and the car run fine but after a few minutes running the engine cuts out and when I turn the key the batterry is dead . I have to recharge again and then starts up again runs fine then turns off . the batterty maybe bad or alternator bad.What else may it be?

I also hear a raddle infront of engine . I shake the water pump and that feels fine, all belts are tight power streering pumpe tight a/c works good .Any thought on that??

when car is driving the wind shield wipes go on by them selfs and the switch is on the off possition Any thoughts on that??

I know im say alot here i just lost my job and have time to work on it.
That you very much

Sounds like a bad alternator, and maybe a weak battery. Have you checked the voltage output of the battery and alternator?
As for your rattle, who can tell from afar? Maybe the fan clipping its shroud.
The windshield wiper gremlin sounds like a faulty switch. It comes apart by pulling off the end cap. Check it out inside.
