Cadence working but not power

Former Member over 4 years ago

My Garmin vector do not show power. Only shows 0 watts. Cadence is working. Firmware is 3.80 and both pedals are paired. Everything seems OK using GC. But not power output even trying with Zwift, Garmin 910XT and Garmin Edge 705

Have you calibrated (zeroed) the power meter?

Yes. It has been sucessfully calibrated by Garmin Connect and Garmin Edge 705 and Garmin 910xt (results = 0 and successfully calibrated apparently)

Is this a Vector 2 or Vector 3 system?

Fw3.80 so should be V3 (and used with GC as wrote)

Remove the pairing from GC (and from your mobile's bluetooth menu if there it is paired accidentaly, or turn off the BT in your mobile for testing). Do not use your Zwift device (is it computer, tablet or what?), switch it also off, and try it only with 705 or 910xt (with these via ANT+ ), if it works, then something wrong via BT.

It is Vector 3

I have removed from mobile the Vector 3 connection through BT and Garmin Connect. I have removed and installed back the batteries (finalizing with the left pedal). Garmin Edge 705 detected the power meter, calibrated again sucessfully but still the same issue (cadence working but not power). Zwift is installed in the mobile, but I only used to cross-check if the problem was on the Garmin Edge.

Are You on latest firmware on 705 and 910XT? I know these are old devices and there is no new fw since 5-6years for these but maybe... regarding Zwift, do You have subscription or trying with the free trial? Didnt You pass the 25km trial limit? Try the Zwift again (do not pair your V3 to your mobile before, let the Zwift app search it in Zwift under power source ), maybe the system BT pairing was the problem (with Zwift), usually lots of users made this mistake with BT devices and with mobile.

I have checked today and I have last firmware for 705 and 910XT. I was suing zwift as free trial and in the first page where you pair the powermeter. Zwift detected the pedals by BT. I am trying to get a newer GPS to verify if the problem persists

Yeah, it is a good idea, via ANT+ it should work with a Edge5xx/8xx , if not working, then the pedals are faulty. I dont know is there any diagnostic report possibility in the GC app to the Garmin? Any other brands have such a feature in their own app and the user can send diagnostic (hidden) datas from powermeter's memory to the HQ if he has problem with the device and the HQ can see the problem much easily and deeply (i never owned V3 just older V1/2 in the past so i dont know what can do the mobile GC with V3)
