We have measured the electron [beta] data spectrum of [sup 35]S with an iron-free magnetic spectrometer. In particular, we have searched for the 17-keV neutrino claimed by various authors to exist at the 0.8--1.1 % level. We have successfully fit our data over a large portion of the spectrum (40--166 keV) and find no evidence for the 17-keV neutrino. The branch is determined to be (0.01[plus minus]0.15)%, which is in serious disagreement (5[sigma]) with the (0.84[plus minus]0.06)% branch claimed by Hime and Jelley.
