I see why this Alternator was on sale for $80, as it's a 'return', sold as new/rebuilt, where someone took out the Bosch voltage regulator and replaced it with some unknown, home repaired brush, regulator. WTF. Regular price is $147 on Amazon.
Being that I wasn't going to swap out today, and the old one was out of the car, I brought the old one to the FLAP to check, and the old Alternator tested fine, 14+volts on there machine. I decided to check/clean all the connections & grounding areas.
After 1st cleaning all connections and grounding areas, I got Idle 12.7v, tops 13.67v.
I charged the battery all the way, and got some better numbers: idle 13.9v, tops, 14.0v
It drops with the headlights & fan running: Idle 12.58v, tops 13.7v.
What voltage are these MBs supposed to get? What do you get?
Thanks

? Is that a solid pulley or the crappy original sheet metal one ? .
I'm hoping Bogy gets back to me soon .

Please take and post photos of it, I'm keen to see if it comes with a pulley and if so, which one as this alternator fits a slew of Mercedes' up to the 1993 model year .
I'm looking for a junk alternator to grab a good used single sheave pulley off of .

The alt I'm replacing is a Bosch rebuilt from 10yrs and 100,000 miles ago.
Should be here this week, so I'll try to swap it out this weekend.

O.K. then .
The original 55 Amp. one is the AL80X, not very popular these days .
A 65 Amp. direct replacement is AL117X, you use your old pulley and this one fits various Mercedes up to the 1992 year model so it should be cheap to find a good used one and slap in a new BOSCH brand regulator and be off to the races with brighter lights and better charging, best of all it fits the original brackets .
I expect to install one of these on an OM617 engine very soon so maybe wait to make sure I know what I'm talking about before $pending any Lolly .
