"Additional info: The voltage sensor works pretty well. I'm using the whole thing over telemetry as well as with the minimOSD.
It's the current I'd be interested in reading properly."

"Hi guys, I think I may be on to something. At least for me, the issue is RESOLVED! I was having the problem that the OSD would boot and then work for a period between 0-120 seconds, usually less than 20 seconds.

Findings: While powering only the…"

"Hah! Strange, but I will have to try that.

I'm powering my my Immersion 5.8 600mW, my FPV Cam and the OSD from a Hobbyking Deadcat Defibrillator, which supposedly gives 12v/1A (and 5v/3A for my Gopro charging). I will try putting the OSD on a…"

The lipo was toast, except from that I think all was good.

I would put the electronics in a jar of rice for a day or two though, and stir it sometimes. That should…"

"Rolf,

I exchanged TX and RX pins on the APM end with each other, and then also exchanged them on the Radio end.
After that, 100% difference. Both…"

"Seems I can't reply to the latest response, so I'm responding in the wrong order here..
I suspected the cable as well, and moved the RX wire to the TX position, but then I did not get any mavlink connection at all. When it is in the original…"

"Yes, all the data shows in MP."

"Yes. It reads the heartbeat when I connect to Mission Planner. It just doesn't read any values from it.
