I had a strange problem. Today I connected the APM to RC, PDB, sonar, xbee as usual ( I am sure in the correct way). I found when I pluged in the battery those blue and red leds were only on for a short time and off after that the apm became dead. No leds were on. I tried to connected it via USB to a labtop, still the same.
I wonder what happened, I just added sonar and lipo monitor and everything remain as they were. On wednesday everything worked well but today suddenly apm died.
Did anyone had similar problem or can anyone help?
Probably the only solution is to buy a new apm. But the apm should not be so fragile. I freak out at what happened today.
