Abstract: A battery terminal harness is provided to connect to a battery with the harness having a first male terminal coupled to a first female battery terminal of one polarity and a second female terminal on the harness coupled to a second male battery terminal of the opposite polarity. To this standard construction an improvement is provided in the harness of an insulating support member with an opening between the harness terminals and each of the male and female harness terminals being mounted on and extending a fixed distance from the support member to mate electrically with its opposite battery terminal. An insulating washer-like resilient plastic cover member having an axial height exceeding the fixed distance of the harness terminals and having tab structure for securement to a harness terminal is provided.
