I got my 2000 SL600's trunk open, installed a new battery. When I try to start, nothing happens when I turn the key to start position. Everything else works, dash lights up perfect, just when I turn the key to the third position, nothing happens. The dash lights stay on, like I never turned the key to start it.

Do you think my starter has locked up? The car is has been in storage for 8 months.

Any help will be greatly appreciated.

Regards,

Al

Out of curiosity, have you tried to start it with the transmisson in N rather than in P?

Yes, i tried. I think it might be a bad relay or something. Seems like it isn't getting any power. MBZ dealer says the key has lost programming and isn't communicating with the brain. I hope not, since car is out of warranty and dealer will rip me off. thanks for the reply.

You can check if there is voltage at the starter, that will tell you if the relay is energizing the circuit or not.

I will check that tomorrow. Do you know which relay it is and where it is located? Thanks for the help.

Regards.

i had the same problem a few months ago. I found a fuse in the boot next to the battery that I hit out while installing the battery. to find the fuse you have to remove the battery. I don't know if yours will have the same fuse.try it you never know. good luck.

Was this the fuse located in one of the two relays, one is green and one is orange, what are these relays for and are there any other electrical components in this area?

The fuse i am talking about is between the battery and the body.It's one loose fuse, looks very odd .I don't know if it is OEM or is connected to some aftermarket system.

The green relay with a 30 amp fuse atop is for the gas pump. The orange is the convertible top.

Also check fuse #18 in the engine compartment. I had no start problem and thinking it was my starter switch. Had the car towed in and the dealer found a defective fuse. Had it replaced and things been fine since.

I had a similar problem when I replaced a dead battery. I had to lock then unlock the doors which must have cleared some security block on my car. Don't know if it applies to yours.

I still can't get my SL600 to start. I have replaced the battery, starter, the two relays above the battery( orange and green), and checked all the fuses. It still does the same thing, speedo lights stay lit, even when I turn key to third position. The starter circuit is not energizing.

Also, keyless entry remote works; but nothing happens when I insert the switchblade in the keylocks. Could it be some anti-theft problem?

Could the neutral safety switch be bad?

Any help will be greatly helpful.

Thanks,

Al

OK, don't panic yet. This is what LeaUK (another forum member) said to do when I had my problem. Get your steering extend all the way out, then move it up and down while have the key turned to position 3 all the while. The car may or may not start. If it does, drive it to a shop and have your ignition starter switch replaced. He actually has a extremely detailed procedure to work on it yourself, if you are a good DIYer. Otherwise, you will be better off paying a professional to handle this task. Here is the URL:
