SRM power meter pairs but send no data

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

SRM power meter pairs but sends no data

I've had this PM for 4 years. It's been great. Then, the battery died... I think. I removed the crank, boxed it up and sent it to SRM for an inspection and likely batter swap. Note: SRM battery swaps are not DIY.

They returned the crank a week later with a report: All's good, updated firmware, replaced battery, tested.

I installed the crank... it was dead. Nothing. Wouldn't pair - the Wahoo Elemnt didn't see it. I tried with a Garmin - same thing.

SRM tech said to send it back in and they'd inspect it. So, removed the crank, boxed it up and sent it back to SRM.

A week later, I get a report: All's good. It was fine out of the box. They're stumped. So, they suggested they loan me a PowerControl 7 (the SRM head unit) to test. Another week goes by - they apparently had to build a PC7 (seriously) and they shipped the crank and computer.

I installed the crank. It paired with the PC7 but only registered 0 for watts and 0 for rpm/cadence. I tried a Wahoo computer - it paired and showed N/A for watts and cadence. I tried with a Garmin 810 - 0 for watts and cadence.

I asked SRM for help... crickets.

Does anyone one have any idea what could be going on? Really wish the nearest dealer wasn't 500 miles away.

Well that sounds like a nightmare, umm, I have zero advice, but I hope it magically starts working again!

You do still have a cadence sensor magnet fitted to your bike don't you??? If there is no magnet or it's not in the correct position, the powermeter will not transmit power/cadence to a headunit....


If you do have the magnet, then SRM needs to do some proper testing for you.


Good luck with it.

I doubt it applies, but w/ Garmin 500/ Quarg,

the Garmin looks for HRM first, & if not found then PM doesn't work.
