Pictorial - Easy Tachometer Fix

[micklongley]

So I am going through each little problem on our new 1980 Mercedes 300SD and I came across some helpful information from this board regarding a quick fix for the tachometer. Mine was not working so I thought I would attempt to fix it. Thankfully it was easier than I thought, but like most things automotive, pictures are worth a lot more than descriptions.



- Locate the tachometer sender (???) on the drivers side fenderwell.



- Unscrew the module from the base unit, make sure your electrical contacts are shiny and in good shape.



- Pull the module from the plastic cap to expose the white silicone material. Find an old flat cigarette butt on the ground and put it between the sender module and the black plastic cap. Reassemble and screw the module back onto the base unit.



- Much to my amazement, this simple fix worked brilliantly, and I hope this pictorial will help someone fix their tach next time there is an idle 5 minutes.

Obviously this will only work in the cases where you need a little more spring in your sender. Your gauge, cabling, etc. need to be good so if this doesn't work for you then you have a more serious problem than I did.

Good luck!
