OK, I was thinking my weak charging isn't the alternator either.
I might check the connections on the back of the alternator, to see if
that helps.
The hydrometer showed one cell just into the red (bad), and the rest on
the line between good and OK.
I need a new battery.
Now I'm checking my Toyota truck, which has an older battery.

The new alternator is slightly better by .2vdc I'm charging the battery now as with all this screwing around and load testing it really drained my battery to the point of not starting. I'm hoping the charge will bring the battery to normal and the very weak Mercedes charging system can then work it's best. If this doesn't work I'll get a new battery. If that doesn't work then there is a wire somewhere with a loose connection under the dash I just wish would be easy to find. It is still taking a long time to come up to 13.7vdc. Way too long. I would think it should instantly go to 14.4 volts. It's not. Lawrence RHOdes
