Hi all,
I have a PowerTap SL 2.21, about four months old. For the first time last night, after riding about four minutes, the computer display of watts and speed suddenly dropped to zero for both values while riding rollers. The transmission icon remained on solid, and the HR and cadence displays continued to work fine. I removed the remounted the computer from the cradle, and it worked fine again for about 20 seconds, then watts and speed dropped to zero again. I seem to be able to repeat this process.
The troubleshooting section in the manual covers only conditions where the transmission icon is not displayed or is blinking. It appears the computer is getting transmission from the hub, but the hub is not transmitting correct data.
I wiped what road grime there was (from two outdoor rides so far this year) off the hub, zeroed torque, ran self test procedures on the computer, wiggled cables, cleaned the contacts, made sure the receiver was mounted properly, etc. with no success. The computer display seems strong with no battery warnings, and I've had the unit only since the beginning of December and haven't ridden that many hours on it, so I assume the batteries are fine. The ride outdoors before this problem occurred was on damp roads, and the bike picked up some dirt from the road, but it wasn't raining and I would hope that amount of dampness wouldn't cause a problem.
Any idea what could be wrong? Any tips would be much appreciated!
Thanks,
Tim
