Hi. One of my arc air controllers has stopped working. I switch in on. The light on top goes on. It runs the car for a few seconds, then stops, the light goes out. I have changed the batteries twice for new ones and tested them in the other controller that works fine. All cars work fine. This is when just using the basic track. No arc app etc. Don't use that much. So don't thinks it's the base unit. Have dismantled the controller, sprayed a bit of contact cleaner around wiped moving parts. No effect.
any suggestions? Do I just need a new one?
