Whilst riding two weekends ago my powertap head unit shut down 22 minutes into the ride, since it was chucking it down with rain I assumed it was waterlogged (although it hadn’t happened before) and didn’t think any more about it. I started today’s ride in cold, dry and glorious sunny conditions but lost the display again. I turned it back on and put it on find, the head unit showed data for the ride up to where it went down but didn’t find the unit.
My thoughts are that it is time to renew the battery in the hub (not done this since I had it new). Does that diagnosis sound correct? You I have to send it back to Powertap via a dealer or is this something that one of their dealers can do in shop?
You can easily change the hub batteries yourself. And, my head unit is notorious for getting water on the pins and shorting it out. Take the head unit off, and clean really good around the pins. I put a glob of vaseline on the pins (in the cradle) to protect water from getting down in there.
I didn’t think it would be anything to do with the pins, as mine is a wireless SL. How do I go about changing the batteries myself, Nick? Is there a link anywhere?

Changing the hub battery is very easy. Its a 5 minute job at most.
Unscrew the large black cap
Carefully pinch the pins to pull out the circuit board with the battery attached,
Remove battery, note battery type
Go to RadioShack to get a new battery
Put the battery in
Replace the circuit board
Put cap back on
It is easy to change the hub batteries, you just need that clack plastic wrench thing that came with it. Does not really sound like batteries to me though. Has the hub icon been blinking? It should do that for a while before you have any issue. Good luck.

Thanks Alex, that’s a very helpful suggestion. I can see why you are connected to a powermeter hire company.
If I could find my manual since emigrating, I could harness your generous assistance.
Chris/Paul, thanks for your help. Chris, what does the hub icon look like? As you can see above I can’t locate my manual ans therefore can’t look it up.
No problem. Let us know when you figure out what the issue is. These things tend to crop up more than once. Unfortunately once they start behaving strangely they are often close to getting a trip home to see mama. Good part is that turn around is usually very fast.

oh please…
spend the what, 8 seconds it takes to find the manual online?? If you can log on to ST, you can manage that. Otherwise, you’ll find useful suggestions such as ‘hit your power tap with a mallet’, hoping the torque tube doesn’t get damaged…
Its pretty easy to change out the batteries in the hub, but be careful removing the battery holder…I ripped off one of the plastic tabs. Doesn’t seem to have hurt it any, but be aware its a bit fragile.
FWIW - my SL 2.4 wireless shut down the exact same way. It had previously given NO indication that the hub batteries were going. Of course, this happened the day before a race…
Be careful when you’re removing the batteries from the hub. The little black platic “fingers” that grasp the batteries can be a bitch, and I’ve broken one changing the batteries. Be gingerly with it!

I provide a manual with all power meters I hire out.
But for everyone else, they are freely available for download online at the Saris / Powertap web page. Since you are online looking at ST, then you can look online here (which took me all of 20 second to find): http://www.saris.com/t-cycleopsSupport.aspx?skinid=2
