possible solution
by: Luigi (Italy)

The inversion direction depend on relay on the board: if relay is not excitet go in one direction if it's excitet go back. The relay is driven from a single transistor: it's need to control that single transistor from a electronic tecnician.
My DIAGNOSTIC ADVANTAGE had a egual problem !
I'm a electronic tecnician !
