PowerTap problem

post #1 of 28
Thread Starter 
Hey guys,

I was wondering whether anyone has had a similar problem. I've recently replaced my PT SL batteries after 3,000km. On Wednesday I got the hub a bit wet, nothing serious - it stays in the house so had a few days to dry out. I used it on Saturday for 6 hours and Sunday for 2, working perfectly on both occassions.

I came to it on Wednesday and it wouldn't work at all. All I got was "---". I checked with a friends wheel and the harness and head are working fine, so it must be the hub - any ideas as to what it might be?

Cheers!

This has happened to me once, I assume the water vapor inside condensed and shorted something out, try opening up the battery thing, and letting it air out for a few days, possibly helping it with a fan.

Mine started working after I did that and changed the batteries.

Re: PowerTap problem

Well, I've opened it up (no sign of water in the battery compartment) and have let it dry for the past 24 hours, tried different combinations of batteries and still no joy - looks like it's going to be heading back stateside - irritatig. What's the usual turnaround for a PT hub refurb?

Make sure you're not in cyclo mode. Go to the current cadence field and hold SELECT for 2 sec.

Make sure you're not in cyclo mode. Go to the current cadence field and push SELECT for 2 sec. Do that repeatedly to toggle to/from cyclo mode.

Re: PowerTap problem

Definitely not in cyclo mode - I dumped someone else PT in and the unit fired up straight away. It's currently sat in the house "hopefully" drying out - just have to see if it has made any difference.

Feels really strange riding the bike without the PT!

Hope yours isn't as bad as mine. I got on the rollers tonight for a spin to see my wattage indications flickering. I hopped off to change the batteries only to find the soldered connection no longer attached. God only knows how long Saris will take to help me at my address in Japan. So much for training with power in December.

I hear ya; maybe try these things:

loosen the cap a bit in case it's too tight.

try batteries you know are good, but be sure not to overtighten the cap.

go to test mode on the cpu and run test 2 and you should see "88" flash.

good luck, Mike

There should be a note in the owner's manual that says "The wire on the battery pack is only soldered to the board so you can pull the batteries out"

I was FREAKING out for no good reason.

Re: PowerTap problem

To be fair I've had great service from Saris in the US - they've posted stuff to me in the UK and I've received orders within two days usually - even repairs to a hub I bought broken on the basis that it might be fixable only took a week and a bit.
My problem is wading through the manual...

Email/phone them, get a Return Authorisation number, delace the hub from wheel and send hub back to Saris in the US.

They are excellent at replacing / repairing I've found. Yes it's a pain and sometimes if you're unlucky to get an early SL there were some with teething problems. Saris simply sent me a new replacement hub. I've had two (I was an early adopter of the SL) like this. Brand new hub each time and not a problem since (wet/rain/whatever). Works a treat.

OK - it's a pain but just do it, fix the prob and you'll be back up in a couple of weeks max I'd say.

Re: PowerTap problem

You don't need to unlace the wheel when you send it to us, depending where you are it might save a few $ on shippnig but that's it. We can do all the same service on a hub or wheel.

The freight cost difference for me was $180. And that was just one way to the US (several quotes through several freight forwarders and Aust Post). Hence I delaced the wheel. I thought OP being from the UK might face a similar problem.

Nah, we just send them back as complete wheels.
