We present the results of a search in pp collisions at s=1.8 TeV for the top quark decaying to a charged Higgs boson (H). We search for dilepton final states from the decay chain ttHH (or HW, or WW) + bbll+X. In a sample of 19.3 pb-1 collected during 1992-93 with the Collider Detector at Fermilab, we observe 2 events with a background estimation of 3.0 1.0 events. Limits at 95% C.L. in the (Mtop,MH) plane are presented. For the case Mtop
