Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hi Im David, thanks for visiting the site. is this a convertible, couple or sedan?
thank you please standby
can you confirm if this is the fuse
ok. please standby. thank you
pull the starter relay. check for 12 volts on any hole on the relay plug.
if you have an owners manual you might want to look in there while i am trying to find it.
ok. i believe this is it
Im not worried about the relay being good. please check for 12 volts in one of the slots with the key off.
ok, not in any slot?
make sure you have a good fuse in the slot
ok, now try it with the key on.
ok. just in 1 slot?
so you have no voltage anywhere with the key off. and 11.20 volts in only 1 slot with the key on? (im not worried about the smaller voltage readings)
Im out of ideas, Im going to open this up to other techs who are more familiar with this system. good luck.
Hi, different expert here. My name is***** you please post the last 8 digits of your vin number?
Thank you, ***** ***** replaced the starter relay?
The starter relay is the relay at position M in the relay box. There is a diode in the relay that may be shorted and is causing the fuse to blow. If the wrong relay is installed it will also cause the problem. The correct part number for the relay is 002 542 23 19 or 002 542 76 19. Remove the relay and see if the fuse blows when you turn the key on. If the fuse does not blow I would replace the relay. I've attached a picture of the relay location below.
Let me know what happens.
Let's not worry about the next step right now. I need to know the outcome of this test first. Just reply back this evening with the results.
The bottom of your relay should be numbered. Jump from terminal 3 to 5 in the box. You should be using a fused jumper lead in case you short something out. If you have no starter operation when jumping from 3 to 5 you need to recheck fuse #7. If the fuse is good and there is 12V present at slot 3 in the box it would indicate a fault with your new starter or with the wiring to the starter. I'm assuming that your battery is fully charged. I've attached a picture of the relay terminals you need to jump in the box.
Yes the key must be on in order to get power to terminal 3 in the box.
Ok, you need to make sure that you have 12V at the jumper wire when the key is on. If you have 12V to the wire it indicates a fault with the new starter or the connections to the starter. Place the wire in terminal 3 and measure the voltage then place it in terminal 5 and measure the voltage. One of the two slots should have 12V with the key on.
I would just connect to the small wire at the starter with a test lead in order to measure the voltage. I would not remove the starter just yet. Click on the image below. Connect your test light or positive voltmeter lead to terminal #3 in the picture then install your jumper lead in the relay box and see if you have 12V at the starter. If you do then I would say your new starter is defective.
Yes, it is probably relocated on the 4matic models.
Yes that sounds like the starter motor is bad. The gear should extend and the starter motor should turn when energizing the starter solenoid. Send me a picture of how you performed your test so I can be sure that you did it correctly.
