No, but they can potentially go off if dropped or mishandled, at least according to the manual.

Re: [MBZ] Monowiper Question
Disconnect the battery ground strap... they don't have an independent power source do they? In 1986 our SL's have a switching boost power supply and a capacitor bank to ensure that there is deployment current during a wreck that might sever the main battery feed. This stuff is, I believe, integrated into the controller in later years. It is, also, likely to be discharged by the time you go to work on the car. It's only there to handle a power failure of a matter of seconds at most. -- Jim ___ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
Re: [MBZ] Monowiper Question
According to the service manual, disconnecting the brains of the system in the passenger side footwell allows a shorting resistor to come into play to prevent an unintended discharge of the bag. At least that was how I understood it.

[MBZ] Monowiper Question
On the 92 300E I recently acquired, I had an issue with the wiper that I wanted to run by the collective list wisdom: While changing lanes I inadvertently turned the wiper switch on the turn signal stalk. The wiper came on, but when I turned the switch back to Off it would not park or shut off. I found that if I caught the wiper at or near the park position with the switch between settings, it would stop. The next time I stopped the car and shut it off, then restarted it with the switch in the Off position, the wiper stayed off. I suspect an issue with the stalk switch, or possibly the contacts in the wiper motor that tell the motor when the arm is in the parked position. I haven't had a chance to consult the service manual, but will be later today. Any direction or suggestions would be appreciated!

I haven't had a chance to consult the service manual, but will be later today. Gettin' a bit new for me, but on an '86 SL I found that somebody had kicked the wiper 'relay' and broken it off. It wouldn't do the intermittent thing, nor would it park. But it always did shut off with the stalk switch. So, based on _that_ car I'd say that your problem was the stalk switch, and that a shot of Caig Deoxit right in the gizzard might do wonders. (I glued that SL relay back together and bridged the broken traces with wire and solder. Worked fine since then.) -- Jim ___ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
Re: [MBZ] Monowiper Question
I have a 96 C280 that had a monowiper with similar issues. It ultimately deteriorated to being unable to stop the wiper blade without turning off the car. I tried replacing the combination switch a couple of times (you would think that I would learn, but this happened over the course of several years and a couple of different dealerships/garages...). The problem for me was not the combination switch but the relay that is located within the main fuse box. Have a look at the following site for the illustrated repair. http://forums.mercedesclub.org.uk/showthread.php?t=62702 The repair suggests taking apart the relay to find the soldered connections that have deteriorated over the years. I found it really difficult to spot the defective connection(s). In the end, I just used a very hot soldering iron on all the connections in the area suggested by the repair.

Re: [MBZ] Monowiper Question
I would try Jim Cathey's suggestion, I've fixed two different stalks by cleaning with a good contact cleaner. One issue on a 123 car was identical to yours, a problem on my 124 car was lack of high beam flash. On the 123 stalk I had to take it completely apart as the contacts I cleaned were inside the end of the stalk. -- Max Dillon Charleston SC '95 E300, '87 300TD ___ ___ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com

Re: [MBZ] Monowiper Question
I pulled the 123 stalk, but it could have been done in situ. End cap can be pried off. 124 was in situ, simply exposed the contact switch at the base and sprayed it off. I don't know if a 124 stalk has an end cap you can pry off; little parts inside, be careful not to lose any... -- Max Dillon Charleston SC '95 E300, '87 300TD ___ ___ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com

Re: [MBZ] Monowiper Question
My '83 240D would get stuck in intermittent mode and nothing would make the wiper stop short of shutting the car off and leaving it off which isn't particularly practical. I ended up pulling the cap off the stalk and shooting it full of contact cleaner. This was before I had deoxit (which I have yet to use) so had to do it about once a week for a month before it seemed to calm down. Then once a month for the year or so until the car expired. -Curt Date: Mon, 16 Jan 2012 13:18:45 -0500 From: Max meadedil...@bellsouth.net To: Mercedes Discussion List mercedes@okiebenz.com Subject: Re: [MBZ] Monowiper Question Message-ID: 16eb1267-2d40-4d5c-adb2-37fb74250...@email.android.com Content-Type: text/plain; charset=UTF-8 I would try Jim Cathey's suggestion, I've fixed two different stalks by cleaning with a good contact cleaner.
