car wouldn't start, pulled voltage regulator, inner brush was worn out, while outer was over 1/4 inch. both were worn with same concave profile. does this spell alternator trouble?
i installed a borrowed voltage regulator, and all seemed ok first day. now, at idle, if i turn the lights on, it changes pitch of the engine. the engine bay is clean, and alternator looks newer even though the car has way over 300k.
Anyone ever experience this: "Old Yella" runs great as I have been retired a little over 2 years now and the car has become a hobby to me as well as my daily driver. With the help of this site I have got the vehicle pretty much re-born. There is one thing that I haven't been able to remedy. The car's water temp guage reads right where Mercedessource states it should 99% of the time,(a picture of the guage reading is on this site or in one of the manuals) just around the 80 degree celsius mark.
When isolating the vacuum pump it takes about 3-4 seconds to build up to 23hg. Is that too long? I have not been able to get a brake booster that holds vacuum is my pump just not able to keep up?
I have a newly acquired 1980 300TD and the first thing I wanted to do was change the transmission fluid. The stick was reading 2 or 2 ½ inches above full at temperature before I did anything, but outside of some issues with the 3rd to 2nd gear kick down, it was well behaved. The gasket was hard and the fluid was very old which is not good news, but the car has suffered fair neglect and I was not too dismayed. The issue of immediate concern was that I retrieved only 6 qts. of fluid from the system, including torque converter. At present I have replaced the fluid to the level I found it at, but am not driving the car. I might guess that the dipstick is either a mismatched junkyard replacement, or maybe the dip tube has been modified or maybe the AT fluid was overfilled.
Just want to verify these issues are covered in the new guide for pre-80 transmissions...just had the transmission throttle linkages adjusted and added the recommended LucasOil. After a few hundred miles, the transmission now flares between 2-3rd and redlines for many seconds before a shift from 1st to second (but only sometimes). It also seems to engage two gears simultaneously sometimes for a short time.
