What happens if the transmitter is switched off?

The car will totally stop twitching. So, I thougt it could be
transmitter that was bad, but I tried with 3 different transmitter and
still the same... Looks as if the receiver has problem treating the
incoming signal?

Looks like it is having problems round the detector / decoder areas. You
probably need more then a DMM to fix this.
