Re: [MBZ] Cruise control 1989 300se problem
This reminds me that I forgot to mention when I got this 240D that on this car I'm going to ONLY push the trip reset while the car is moving. I think the theory that it breaks the tip is an old wives tale, I don't understand how it could possibly put any more strain on the thing... As to your question no, the CC takes its signal from the speedo which is upstream of the ODO which is upstream of the trip. -Curt Date: Thu, 11 Nov 2010 01:06:25 -0600 From: David White kathma...@cableone.net To: mercedes@okiebenz.com Subject: [MBZ] Cruise control 1989 300se problem Message-ID: aanlktikepfcagxehcg5puucnex2j9qnqqwshkz62k...@mail.gmail.com Content-Type: text/plain; charset=ISO-8859-1 A question, could a stripped trip odometer cause the cruise control to intermittently fail?

Re: [MBZ] Cruise control 1989 300se problem
It is a myth that resetting the trip meter while in motion will damage anything. Regardless, the odometer has nothing to do with the cruise control.

My guess is the control module but I dunno. On a W123, the cruise control pickup is on the input of the speedometer, directly driven by the speedometer cable. I don't know about the '89 300SE. Do you have a mechanical or an electronic speedometer?

Re: [MBZ] Cruise control 1989 300se problem
Sounds to me like you need to implement the Jim Cathey plan: Test to isolate component at fault (my bet is on the CC circuit board), and then fix or replace. I'll bet that if you re-solder all the circuit board connections, your troubles will be vanquished. http://userweb.windwireless.net/~jimc/mamerepairs.html -Max From: mercedes-boun...@okiebenz.com on behalf of David White Sent: Thu 11/11/2010 2:06 AM To: mercedes@okiebenz.com Subject: [MBZ] Cruise control 1989 300se problem A question, could a stripped trip odometer cause the cruise control to intermittently fail?

It's a fine distinction but one that doesn't matter in practice. If your tripmeter gears are already loose, resetting it in motion will make the failure obvious by inducing particular symptoms---the Chinese-water-torture clicking the mechanism makes as it tries to turn forward every 1/nth of a tenth of a mile but can't. I'd call that damage! Have had it happen on two W124s now. The first one I sold (for other reasons!), and got an angry call from the buyer about an hour after he drove off in the car. Buyer: How do I stop this @#%*# clicking? Me: Did you just stop to fill up the car? Him: Yes. Me: And then you reset the tripmeter? Him: Of course. Me: While the car was moving? Him: Well, I was just pulling out of the gas station. Barely moving. Me: I told you not to do that. There weren't any more phone calls after I told him the trick to make it stop, so I guess he learned his lesson.

Re: [MBZ] Cruise control 1989 300se problem
could a stripped trip odometer cause the cruise control to intermittently fail? No, not really. Spastic operation is almost always the solder joints failing in the amplifier. My wife's 560SL has just started acting up that way. One of our last ones to _not_ have this problem. I've also had one that didn't want to work, but that did work normally when it was working. That turned out to be a damaged stalk switch, its 'off' switch was overly sensitive. These faults in a 10:1 ratio or so. -- 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://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
