| Replaced Battery - What happened?
I replaced the original battery in my SLK230 with another MB battery. I knew I would need the code for the radio. But several other strange things happened when starting the car.
The Fuel and Temp gauges are not correct; the fuel gauge actually spins all the way around. The outside temp is incorrect and now is Celsius. And the odometer is all dashes now(-------).
Any ideas what has happened? Does something have to be reset? For now I think I will check the fuses. |
