This is a new build, 420S. After putting the battery in, I checked all the lights, flashers and indicators. Everything worked fine. On my first test drive around the neighborhood, I put the turn signal on at the second or third turn, Half-way through the turn, the beeping stopped. The turn signals stopped working. After getting back to the house, checked everything for loose connections but still no flashers or turn indicators. Took the car out today for a short test drive and the turn signal worked for about three flashes then again, no beeping and no flashers. Got back to the house and pulled all the fuses to see if any were burnt, all were fine. Open to any trouble-shooting ideas. Thanks to all for any help.
