  1. Excellent, just what I need, I thought. I could remove some screws and wires and spray some contact cleaner spray. Total failure. I didn't even get past stage 1, to remove the first four screws. Two of them seem to be connected to some rubber-thingy and all that happens when I unscrew them is that the rubber gets twisted. Nothing gets loose. I guess I have to hand the lawnmover over to the repairman after all 🙁

  2. Informative and good. What kind of spray did you use to clean the contacts ?
