I've an old Powertap Pro with G3 Internals that is now giving me some random 2000+ Watt spikes.
This doesn't happen every ride, minimum cost to have it serviced/calibrated is £160 or so, which for the age makes it pretty much a write off.
Is there anything else that can be checked at home? or is it knackered.
