I'm having trouble with my Powertap GS and it's driving me nuts.
A few weeks ago, it died during a ride. OK, no prob. I replaced the battery, but 5 mins into my next ride, my Garmin told me the battery was low, then power readings were gone.
Since then, I have replaced 3 batteries and I get the same reading every time. 5 mins of power, then I get the same notice, then it dies.
So, I removed the pm, updated the firmware, cleaned off all the contact points, ensured the o ring is properly seated, but nothing works. It dies after 5 mins every time.
I also tried multiple devices and apps, to include trainerroad (PC), Garmin (watch), and even the strava app (phone) and they all read it. They also all pick up my HR monitor, cadence sensor, etc...
I will contact Saris today, but if you guys have any suggestions, pls let me know.
Please let me know how you go on - could be coincidence but I have a similar issue on a GS ...
On another note, does anyone know the led flashing functions / messages from the led inside the power cap ?
