Can A Bad Battery Cause Electric Power Steering Problems. It connects the steering wheel and column to what is called the intermediate steering shaft. Yes it could be so check the condition of the battery.
You could pin power steering problems on a bad battery only if the battery is bad enough that it overworks the charging system -- causing the alternator to fail which in turn overworks the belt that powers both the power steering pump and the alternator causing the belt to fail. With the engine running check again at the terminals and you should get approx 145V. Disconnecting the battery forces the ecu to reset so may clear some fault codes and on our Clio with electric power steering the steering is the last light to go out on the dash on start up so it may be waiting for the voltage to rise above a set point a bad battery or alternator could stop the volts getting high enough to arm the power steering.

Lets break it down. You should still be able to steer the car even without power assistance. Interestingly enough when people have problems with the General Motors positive battery cable they often complain about the power door lock actuators activating by themselves. The big catch about electric motor and arch is that it is non-repairable and one has to replace it with the new one.
