MB W115 -75 not charging and turn signals do not work

¤¤Race_Chick¤¤ · 3. November 2012

It's like my Mercedes W115 has two problems that I do not know how to fix.

Battery light glows all the time in the coupe, it glows weakly when I do not press the gas but the brighter if I gas.
I changed the generator coal, replaced cables and connectors, but no results.

Then do not turn signals work, when I put the turn signal it gives no sound. Hazard lights work and I have tried to scare off the turn signal lights by pulling off the hazard warning flashers and then regular lights but it does not work.

The fuses are intact and new exchanged.

hi, at first i think you need to change/replace the alternator, only change the coals might not bring the result that you want, cause often there´s a problem with the rotor of the alternator , where the coals get there contact from.

second thing: if your relais/ecu is ok (try another from a same typical car) then you might change the switsch for the indicators/wipers- it often makes this kind of problems.

good luck

I changed the alternator and cleaned a lot of cables around the engine compartment, when I test start so work load, work lights, fog lights, etc.

But now the problem .... I was out and test drive a turn and then start the headlights to "pulse" and the temperature steps from normal 80 degrees to near 90 degrees, then the idle start idling walking up on the small and the charging light start weak light when idle went down and off when idle raised ... late when I went home and stood in the yard so the car went as usual, when it had no faults at all and everything work just superb perfect

did you checked the connectorcable on the starter? what about your battery? maybe it has a short internal.
or your surgerelay isnt work. thats now to check

okay i bought a new coal again and now it seems to have fixed itself with the charge.
But now a new problem yet ..... Yesterday I changed the coolant in the car (the old one was rusty brown), after the change, so does the temperature to almost 94 degrees! Before it stood steady at 80 degrees .....
When I turn off the car and let it cool to 40 degrees so I tried to start again and then rose slowly to 80, yes it is quite normal on late in less than 1 second, it flies in the rocket to 94 degrees! I do not get it, I did nothing wrong, I did loose bottom hose on the radiator and the hose to the heater so all old water did come out, then tighten everything back on the filled up ...

change the thermostat !

it turned out that there was air in the system so it's fixed now, now is the temperature at 80 degrees.

But now stop the charge again, it charges only 11 volts and it is supposed to charge the 14 volts

I think oyu have somewhere in your car an user, like Radio amplifier and so...
Are the connectors all right or is there an relay problem...can you gauge your alternator directly??

Stereo is directly connected and the clock is running all the time.
We measured the generator yesterday and it stood at 11 .... Could be that the alternator cole must be filed on the edges so that it reaches down to that wheel in the generator. The old generator filed coals a little crooked
