What shape were the donor brushes in? Also, what brand of alternator - Bosch?

Nice work. Have you installed a relay on your ignition yet? That had the greatest effect for me. I upgraded all the ignition/starting and charging wires to much beefier stuff but it wasn't 'right' until I did the relay as well. If you are running a bigger alternator but still no relay you run the risk of frying your ignition switch still.

I like it. Alternator refurbs are somehow very satisfying!  Plus, there is so much support for older Benzes, parts will never be an issue.

Good one to remember.

I worked on older Benzes for about 8 months in 1994. I was amazed at what you could buy for them. Problem was: they were built like trucks and drove like them too.

I will say a 300 SEL 6.3 in the wet is "Interesting"!

I am sure they drive better much better these days, but without exception look like s**t IMO.

Hi, I'm looking at doing this modification after fitting Hella H4/H1 combination in US buckets with big watt globes,relays wiring etc all upgraded to suit
Was just looking for the Bosch Al80X alternator and wanted to clarify that this is the one you used, it appears to be only 55amp ?

That explains it, thanks very much for the links I was about to order the 150amp one
then found these first one should be direct fit, I'm going to do some homework to see if the original front plate will fit the second one

I love my Benzes, but I can tell you that as far as Type 247 BMW motorcycles go, there is an entire industry devoted to replacing Bosch components (that I stick to).  Hard to argue with the efficacy of a Nippondenso starter motor modified from a Toyota truck unit that weighs less, turns harder, draws far less current and doesn't have the failure-prone glued in magnets.  Upping the 280W alternator to an aftermarket 400W Omega is another potential improvement.
