The paper presents experimental results obtained as part of the GEMCAR European project using the VERIFY EMP simulator belonging to the Swiss Defense Procurement Agency (Spiez). VERIFY generates a vertically polarized electric field with a rise time of 0.9 ns and an FWHM of 24 ns. The working volume is 4×4×2.5 m³ and the maximum E-field amplitude is 100 kV/m. Two experimental models for the vehicle and the cable harness were used for the tests. Measurements of electric and magnetic fields within the vehicle, as well as induced currents on the harness were performed, considering two types of illumination (front and side) and different harness terminations. It is shown in particular that the presence of the car could result in an enhancement of the induced current in the wiring system
