Hello there, I have recently purchased a Countax C800H 4x4 mower with known issues. The main problem Is that the electric deck lift is broken. I have checked the lifting ram by applying 12v to the correct pins in the plug and can get it to lift and lower by changing polarity. Have just fitted a £100 new Deck height module Of which made no change to the problem, still doesn't move with the dial on the dash. Now the dial is £200 for some reason as it's only a tiny part. Is it likely that it's the dial at fault? Can it be tested in any way?
