Hello. Bought my som a second hand set for Xmas, it worked fine for 2 days then stopped. The cars will run fine on power 2 (on the hand cobtrollers) but 3 or 4 they just start stop and won't run. Even if I just put them on the power supply bit of track. On setting 2 they run perfectly. Can anyone please help as I now have a very disappointed boy
