Problems with steering in driving games.

Test the steering in the Input/Output test. Check whether the steering produces the correct values in the left, center and right position. If not readjust the steering potentiometer as described in the operation manual.

Turn the steering wheel slowly and see if the values are changing smoothly. Jerky changes could mean a faulty potentiometer.

If the value does not change at all, check whether there is +5V connected across the outside terminals of the potentiometer. Measure the voltage directly across these terminals. This way you are making sure that both the ground wire and +5V wire are connected to the pot.

The voltage on the center terminal should vary as you turn the steering. If not the potentiometer has to be replaced.
