I have problem with my 560sl 86 .The batterary is dead but i charge it and engine runs for 10 to 15 mins then stops .The last time i drove it the tech jumped up tp 4000 rpms when i was only going 25 miles per hour .Also the pully is making noise on the alterator.
Where should i start replace alterator and what else . I here talk about OVP (Overload Protection Relay) Then the ABS relay .I checked all cables and they are fine.I located the OVP under dash .
