Hello everyone. I am confused because I built a quad that has an issue. I see the OSD working in the  DJI goggles but mah used stays at 0.00 and I use the RSSI for LQ on AUX 8 and the number starts at 80 and drops fast as I fly away from myself. My transmitter starts saying telemetry lost. My other quad works perfectly and has the same crossfire receiver using AUX 8 for link quality as RSSI and the battery Mah used works perfect. What did I do wrong on this ? 

Diff all and Dump files here. Thank you all.

Here is the diff all and dump from the perfect working Apex if that helps out.

Try running the following CLI commands to see if it makes any difference. After doing this, check that the LiPo voltage reading in the OSD is still also working OK.

I ran them and now no battery voltage comes up just 0.00 ?

Try this instead...

Negative sir. Just 0.00 on battery now. RSSI shows 80% also. Hopefully that’s something I did wrong in setting up the TX.

In that case put it back to the original configuration using the commands below and then check that the current sensing wire between the FC and ESC is connected properly and has continuity.

ok that’s back to normal now. I figured out the link quality issue too. The Aux 4 that’s really channel 8 was not set in the receiver tab in RSSI channel. I set it to AUX 4 and now that’s good to go. Do you think the wire between the ESC and Flight controller could be the issue ? The hobbywing did come with different cables with no explanation on what one to use ?

Which Hobbywing ESC are you using?

The X rotor 60A 4-in-1 & flight controller F7.

OK. I see that you have the complete XRotor F7 Stack, in which case the wiring harness cable between the ESC and the FC should be wired correctly. Try re-seating both connectors by unplugging and re-plugging them. And while they are out, use a magnifying glass to check inside the sockets for any bent or damaged pins.

I took it apart and unplugged the cable between the flight controller and esc. No issues and I used a magnifying glass to inspect it. No bent pins or damaged cables. It does seem odd that the esc and flight controller came with multiple cables. One cable looks like the correct one but the quad won’t arm with it installed as it has two red wires. The other cables have the short connector on both sides for the flight controller and another one has the wider connector for the esc on both sides. The only other cable is the one that works and everything functions like normal. I’ll look into the wiring diagram in the morning. The cable that functions does have one wire that is completely gone like it was never a part of it. Maybe that’s it. To be continued… thank you for helping me SnowLeopardFPV.

Have a photo? Must have been cause by a short.

It's unfortunate that Hobbywing don't put out more detailed info about their stack and the accessories it comes with. If you can post some photos of the wiring harnesses it came supplied with, that would certainly help a bit.

The stack comes with multiple connectors. I had the same issue your using the wrong supplied cable. Look at the directions for the correct pin out for the connector. One side the negative and current wires are backwards.

Here are a couple of pictures.
