In this work, we present the results of precise measurements of the resistivity of YNi2B2C single crystals with Tc = 15.5 K as a function of the temperature, and analyze the experimental data in the framework of the Bloch-Gr\"{u}neisen theory and electron-phonon coupling. The transport electron-phonon spectral function that best fits the resistivity data is then inserted in the real-axis Eliashberg equations, which are directly solved to determine the normalized tunneling conductance both in s- and d-wave symmetry.
