plinker17722 First if you have ant contacts like the one in the picture i would clean them all up to start with . Might even be the battery clamps fouled up inside .. Earth return problems are a major factor in failure of 90% of all electrical issues .

fildyb Have you resolved this issue? It seems I have the same problem.

ianrandom Good call, could well be a faulty alternator, especially if its a cheaper one. But even if not, don't rule it out.

I keep a little cheap charge Led indicator that tells me how many volts, just in case. Plugs into the cigarette lighter. You could try that as an easy option and you can see how it behave while running.

STILL NOODLIING OUT THE CHARGING ISSUE

Here is specific vehicle information:

1983 280SE EURO MODEL MERCEDES
THE ENGINE NUMBER IS 110 989 126 155
VIN # IS WDB 126 02211 207 9595

I will run a good ground from the engine to the battery to see what happens.
will take a few days since the two piece alternator pulley spun and will need to be replaced.

Also....can i check the alternator by measuring voltage...see pic.

the new alternator may be defective.

aam Ignition key on. All dash warning lights on.
Check the battery light, it should be ON.
If its not, replace the bulb, or, broken disconnected wire.

The light is the signal/sensor, that makes the alternator charge.

Regards,
aam.

ianrandom All I can think of is checking the cables especially the ground.
