HORN - Renovating...and with questions
« on: March 10, 2019, 04:00:59 PM »
Dear friends,

On my MB170S, the two horns are renovated (in good condition...), BUT sounds terrible.
The adjustment screw on the back, and the center screw in front doesnt really help.
The sound frequency is way too low and sounds more like a buzzer than a horn.
I feel abit stupid, as the mechanics and electronics are very basic...

Any good ideas?

You have to install a relay.
I had the same problem with a friends car.
One horn worked OK but when connecting two horns the signal through the steeringwheel harness the power was not enough for two horns.

Try to disconnect one horn...
