ABS light on, Speedo Dead...Fixed!
After a recent jump start my daughter's 1993 C180 developed 2 problems.
The ABS Light stayed on and the speedo didn't work.
Fuses appeared OK (Couldn't find an ABS or speedo fuse)
A search of the forums suggested resetting the car by disconnecting the battery but that didn't work.
Other posts pointed to the OVP (Over Voltage Protection Relay) near the ECU (Under the left side of the Hood/Bonnet near the firewall. A silver relay box with a black top about 50mm/2" square.)
Armed with a can of contact cleaner to clean the plug terminals I noticed a clear plastic lid with a 10A fuse under it.
The fuse had blown and everything works again now that it's replaced.
Thanks to prior posters who led me in the right direction
