Just installed my new Vector 3S and all I can get is cadence. Will register 40+W if I go flat out otherwise it reads 0 or something <15W. Have tried 2x 510 head units, a 920xt and Fenix 5 as well as GC on iPhone, same results. Have tried taking the battery cover off and reconnecting but still nothing. Pretty pi**ed as I'm of to IMNZ on Wednesday and all I've got to show for $850 are a couple of paperweights.
Any ideas?
