My K2 worked fine until about 9 months ago. However, now the DVR switches on with the bike’s ignition, runs through its start up checks (all the lights flash on and off for a few seconds) but then shuts down. The power supply blue led light is on ands stays on throughout. The switched live wire is connected to the live supply to the rear brake light switch; I‘ve checked that the circuit is permanently live. The bike is a 40+ year old Suzuki GS1000 with conventional electrics (ie not CAN-BUS). Nothing has changed in the way the K2 is installed now compared with when it did work previously.
