I have a MARSA4 Flight Computer that I am wanting to sell on TRF. I picked this unit up at an auction at our local club and I have never used it. I would like someone to enjoy it; however when I plugged a 9V battery and switched it on to see if it worked a "Sensor Fault" message came on. Can someone help me to understand if this unit isn't working. I don't want to sell a broken item to another rocketeer.
Thank you,
Mark
