Happy Thanksgiving to all!

One of my biggest fears was leaving the lights on and killing the battery. Well, I went and did it. I recharged the battery with a charger.

I resync'd the windows, inserted the code for the radio, but now my attenna is not going up or down even though the I hear the motor spinning. The other thing which is interesting is my convertible top button light is on steady and the up arrow lights in the roll bar switch on the dash is glowing steady as well. I have the hardtop on and obviously because of this situation it is not releasing the hardtop from the locked position.

Is there something I am supposed to do to resync everything or did I mess something up?

i have heard of similar problems, search. cause of what i read a long time ago when my batt died i did not even try to recharge or jump, i just went out and bought a brand new one (interstate battery). so far so good it all works.

as for your antenna i think is just a coincidence that it doesnt work, i dont believe its related.

I agree with Carlos about the antenna. Regarding the top, a fault code is probably set within the controller that is inhibiting operation. The only documented procedure for resetting the code is to use an advanced scan tool that would typically be had only by a Mercedes service shop.

Hi people, I just wanted to know if you can confirm the lenght of the antenna mast while fully extended.

Thanks in advance.

Cheers.

Carlos....I'm thinking of getting an Interstate battery as well before the Winter sets in...The correct number is "MTP (Megatron Plus) - 93".....Correct??

TIA

i dont know the correct number, i took the car to the mechanic and he replaced it. i'll try to find out the part number.

Antenna sticking can often be fixed by giving it a helping hand (pull firmly) whilst
the motor is running in the "up" mode. When released, even an inch or so, squirt WD40 or similar down inside and continue attempting to operate. Antenna often stick because they are dirty.
The easiest way to charge your battery is via the Cigar lighter using an adapter.
I use a battery conditioner all the time, this has the advantage of not requiring any attention, even if you dont run your car for months, it will still start first time and no loss of computer memories

On my 1999 SL500 i replaced the original MB battery with an:

Interstate #00MTP-93 battery. 850CCA., 1065 CA., 155 RC(min), & a 85month warranty.

Consumer Reports mag does rate Interstate batteries very highly, but I've been happy with mine.

Battery tenders are an excellent idea. Great care must be taken with chargers though. While my 95 SL320 was at a body shop for collision repair the battery ran down. The charger they used blew some kind of computer located in the lower part of the engine compartment. Repair cost $1500.
