I have a MoMo Force feedback that the foot pedals recently acted erratically I thought it was because I tripped over the wire,I checked the wires to the circuit board.On the back side I found some build up of crud bridging maybe 3 of the terminals.I cleaned off the crud and now a perfect both pedals to the metal.
The only thing being effected is the pedals,everything else-works fine,I've replaced a few components before on circuit boards.but had had a tv electrition friend tell me what to replace.
Does anyone know what I should fix here? Or a schematic I could look at that might help?
