Now that you know how to test, assuming you'd be willing to spend time at a pick-n-pull, here are the other models that use the same sensors on the front axle, mined from the free on-line EPC (http://epc.startekinfo.com/epc/home.jsp). I assumed that a 1989 300SE is a 126.024, someone correct me if wrong.
The part looks like it has been revised four times - I wonder if there is a recall on this? Worth asking your dealer's service manager perhaps? Part number is 126 540 25 17 for front left, 126 540 26 17 for front right. 300SEL 380SE 420SEL 500SEL 560SEL 560SEC 300SD 300SDL 350SD 350SDL Plus all 123s in Euro trim that have ABS. -Max -----Original Message----- From: mercedes-boun...@okiebenz.com [mailto:mercedes-boun...@okiebenz.com] On Behalf Of Jim Cathey Sent: Thursday, April 22, 2010 10:36 PM To: Mercedes Discussion List Subject: Re: [MBZ] 1989 Mercedes 300SE Brake weirdness > Is there a way to test the pickups with a multimeter? Connect multimeter on AC voltage in parallel to the (connected) pickup, and look for a smoothly rising voltage (and frequency) signal as you speed up. Needs to be equal on all three sensors, no jitters. -- 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 _______________________________________ 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
