Garmin SL40/intercom trubleshooting
I have a legacy RV12 with the Dynon D180 and a Garmin SL40. I flew today and realized the Radio will neither transmit nor receive but it powers up. The intercom worked fine I could hear myself talk. I switched to bypass and there was no difference. I tried the passenger side headset, but still nothing. The radio does not indicate I am transmitting when I key the push-to-talk buttons on the sticks. I removed the radio and tried contact cleaner on the connectors, but still no luck.
Has anyone experienced a similar situation? Any ideas on where to start troubleshooting? I have had no problems with this radio/intercom for 12 years.
