What's wrong with my Mercedes?

Unknown battery drain, electrical shorts, blown fuses - these can be difficult to isolate!

Common to all 126 sedans 1981 to 1991 - you hear the motor mechanism running but glass is not moving or it's binding

It just may not be wired properly. Most likely it is NOT the antenna.

If it is happening on a regular basis it probably is not bad glow plugs

It is possible to do this but you have to cut the black cap off first.

This is one of Kent’s favorite tools to have around the shop

You can do it with commercial products or something in the cupboard

We share with you the factory instructions for most models from the late 1970's to late 1980's

Knowing what fuse does what is a must when troubleshooting electrical problems

Neglect is probably the No. 1 Cause of your Benz not starting

There is a quick fix as well as a more permanent repair

Originals are hard to fix and not available new - Universal new antenna may be best option

If the wiring plug falls apart on you, you won't know what coded wires go where!!!

This could be caused by one or even a combination of three things.

Do not assume it is just a bad battery! Diagnose first...

If you are constantly having to replace glow plugs do not immediately blame the plugs! Ream the carbon!
