Upgrading Alternator Amps for DTC

Greetings from Columbus, Ohio. My 1982 Mercedes 300D Turbo Diesel has a glorious Mercedessource DTC system! Only problem I am experiencing is that the alternator can not reliably keep up with the electrical demands. What ampere level would be a good upgrade (150 amp to 300 amp?) and do you have any specific brand/model of alternator you recommend? Trying to eliminate the risk of producing too many amperes as well (if that is even a concern). Many thanks and keep on Greasing! --- Chris Konik

Door Locks 93 300D 2.5

After locking my doors with the key all four lock knobs pop open on there own after about 45-60 sec. I can hear a wirring sound comming from the back seat. I am assuming I have a vacuum leak somewhere or a malfunctioned pump under the back seat. Could the door vacuum actuators be faulty? I am trying to keep this simple at first before I need to take the door panels off. Thanks for your help Mike Stillwater, Minnesota

AT Metal Cooler Line Leak

I have an '83 W123 & have just noticed a fast drip coming from the area of the automatic transmission cooler line on the right/passenger side - along the engine & at the very point where the line bolts to the oil pan. I assume that this is the same problem mentioned in the "Alert" section. Question is, aside from the preventative fuel hose replacement, what sort of actual "fix" can be applied to stop & solve the leak? Has anyone fully repaired a leaking AT cooler (metal) line? thanks, Kieran- NJ

Early 90's electrical wiring harness problems

Just purchased a 1991 300sl, 104,000 miles. No problems to report, however, been reading about electrical wiring harness problems affecting certain model years from 1992-1996. Some report problems with the 1991 model years to 1996. does anyone know exactly what model years, and/or model cars/engines were affected? trying to figure out if I need to start a more detailed search under the hood. Can anyone offer any input?
