87 560 SL electrical problem...

[E320Coup]

My 87 560SL has run perfectly since I purchased it 2 years ago, but last week I drove it a short distance to town and it died on me, like I was out of gas. Checked the gauge and fuel was fine, but noticed that my lights were dim and it would not turn over. Called a friend and sure enough jump starting worked? Thought it might be just a bad battery so I replaced it.

2 days later, the same thing happened, fortunately, I was in the driveway.

Sound like a charging problem or is something draining the electrical system?

I have a meter and know how to use it...any help would be appreciated.

Alternator brushes? Cheap and easy fix if that's what the problem is.
