Unfortunately, after 2 months of use is down the device. Amazon had no substitute, but refunded the price without returning. Thus, I have completely dismantled the device. Everything is screwed and can be super disassemble thus. The error put the switch. This is fortunately a double switch with two rows of soldering, the switch separately. The one that was connected to the engine, was defective. The other turned yet. Simply the wires resoldered on the other strip, screwed together again and off we went again.
Against throwaway !!
