i have a 1991 300e 3.0 engine. i had a problem with the alternator, so i had it rebuilt, it was working fine till i went on the highway today, and i had the a/c on and stuff. then suddenly an hour into the drive, the abs light and srs light come on, then the radio and blower motor come on, then things start shutting off, then the car start slowing down and cutting off while i try to give it more gas, then suddenly it goes back to normal.
it never fully turned off.
but i did notice that when the lights start coming on, if i put it in nuetral, i get all poower back and car goes fine for a few kms.
it seems to me that something is lose, b/c this only happened on the highway, not in the city when i got back. and it could happen 10 times in a row, or go away for 45 mins. which is wierd.
possibly the wind moving something that makes it lose power, im not sure.
any ideas?
considering irebuilt the alternator and the voltage regulator has new brushes.
thanks
