Powertap says "---"

Since 2001, over 90,000 cyclist's have joined Cycling Forums to discuss topics from general cycling to equipment, training, racing and travel or vacation destinations (especially in europe during the tour de france). We also feature an great deals in our online store, 100's of articles, classifieds and product reviews.

I've been having some problems with my PT SL on my past couple of rides and I'm hoping someone who's had the same problem can fill me in. I don't have access to the manual that came with the PT as I'm moving house and in temporary accommodation. The unit works perfectly for between 1 and 3 hours, but then the computer screen will say "---" in the current power display and "--" in the current speed display. Then for a while it will intermittently work for a few seconds and then go back to the ---. Eventually it just turns itself off.



I just replaced the battery in the computer a couple of months ago and it doesn't appear to be low on juice. Is this likely to be a problem with the computer, the wiring harness, or the hub? Is there a quick fix?

Thanks for any help!

I've had this happen with a fraying wire in a harness as well.
