In this paper we present recent results from a continuing investigation of cataclysmic variables in the 500 to 1700 A region with the Voyager ultraviolet spectrometers. Observations of outbursts show a substantial delay (~0.5 day) in the rise to maximum in the FUV (912–1200 Å) with respect to optical wavelengths. Both FUV and optical light decline simultaneously. Flux distributions show a significant flattening in the FUV and with the possible exception of CPD-48 1577 no EUV flux has been observed in any catalclysmic variable. CPD-48 1577 shows a marginal, 2 σ EUV flux.
