Hi guys,
I bought a 1988 Mercedes 260E about a year ago with 114 K miles. I have two problems with the car. Once in a while the ABS light (sometimes the SRS or the brake light) goes on for a short time and at that time the alternator is charging below 10 Volts (according to the manual). I lose the idling and the engine runs a little rough. The alternator was replaced in April, but this problem keeps coming back. Can you give me an idea where to look for the problem? Maybe there is a bad ground somewhere or a corroded connector?
The second problem is the acceleration from standing position when the engine has reached the operating temperature. It is kind of sluggish until it shifts to the 3rd gear, although there is no problem when the engine is cold. Any idea what could cause this?
Any help is greatly appreciated.

hi,
sounds like the problem may be with your battery try replacing it with a new fully charged battery test the car fully if the problem doesnt occur within usual time i.e after running for 10mins ect, run the car for two weeks if the problem returns after this time replace alternator as old battery has over worked it also check earth strap under nearside front chassis to engine just behind the front wheel give it a tug make sure its secure and not broken this could also cause charging problems but car doesnt usually start if this earth strap is broken.
hope this helps,
good luck!!
