thanks for the video, it is very instrumental. I have same exact issue on my tachometer, burnt resistor. I replaced 56 ohm rate at 1/2 watt resistor and 100 microfarad / 10 V tank capacitor. It fixed the inoperable tachometer.

Fix of the time clock is often replacing a burnt condensator 16V 100uF. 50ct piece.

What is the value of the resistor that failed on the speedo? I'll guess it might be the same as the other next to it but I can't make out the color code. For the clock, replace the two electrolytic capacitors, this is the common failure on the clocks.

Hi, for the clock it is one of the elcos. I have repaired a clock on a W126. There are some German W126 sites that show which elco it is. A new clock is very expensive.

Many tanks !! I have the same resistor burnt on tacho of my sl 380 . The resistor value ins the same 56 ohm?

Usually the clock does not work because the capacitors are dried out and need to be replaced. Easy fix.

Yes, i fixed my clock by replacing the capacitors. It was an easy $2.00 fix- speedo shops charge $145.00 for it. Now to figure out the tach...

I found this on the web: You need 100mfd caps with a 20-40vdc rating. (RadioShack.com) I repaired mine the same way. Also you can desolder one of yours and take it to an electronics supply and get something similar. If you can solder at all, its an easy fix- if not, most speedo shops charge about $140.00 to fix your clock. The parts to DIY are less than $4.00.

I have a 1990 300D and my tachometer works intermitently. Any ideas? Where does it get the signal?

How would you repair the tachometer on a 1987 300D w124, I had the same exact loose resistor that you had on your video. I replaced it but the tach still does not work. Could I modify a gasser tach to work, and how would you check it with out installing into the car for a test. Thanks for your great videos Joe

The tach in my '91 300-SEL M103 engine does not work - it's a gas car. Not sure if my tach assy. is similar to the one in this video. My clock does work. Speedometer/odometer/trip meter are also not working. Most likely I'll send to Rick Borth in Austin Tx - speedometer.com
