Scott, Good question-previously it was internal regulator. Symptom is dash warning light comes on and stays on. Also electrical smell. I used to change my own but can't really do that now. In the days of generators, used to change brushes along side of the road or even early alternators had replaceable diodes. It is not the bearings- no bearing noise-my old Indy went out of business-I need to see if I think this guy is doing all the diagnostics he can and not just part changing since they are on a one year warranty. He has checked grounds, battery, etc. I will give him one more chance on this-if this alternator fails, I may have to switch to OEM from Rusty or try one of his remans. Two alternators ago, the one was bad right out of the box. He sent it back and got another one-so I guess that makes 4 in about 18 months. I was wondering if other brands of remans are available for the 240D.

Were all failures similar? The brushes and regulator are an easily replaceable unit that I've changed from below with the car on its wheels (not jacked), is that what failed? Belt tension is important; too lose and you won't charge, too tight and it will ruin the alternator bearings. The Bosch reman I got from Rusty still works fine. I did have a problem where a burr on the pulley ate belts until I discovered the cause (operator error while swapping the pulley to the reman alternator). Scott Ritchey Kittrell NC 1982 300SD 220K 1979 300TD 350K ------------------------------------------- Just had the 3rd remanufactured Bosch alternator go out and need to be replaced on the Green Goddess.. This is the third one in a little over a year. I know Curt Raymond that problem with his 240D and Bosch reman alternators before he sold it. Anyone else have any experience with these? This is the second Indy to work on it-can't find any 'cause'. When I ask about cause I get what the Car Talk guys call 'the mechanic's shrug. I have two specific questions: Has there been a run of bad reman Bosch alternators? Any problems with the electrical system that could be frying the alternators? Thanks.
