This is a fuse holder, it does the job. I replaced the original fuse that came with the kit as it had not blown but was not passing any voltage. I replaced it with a new gold plated one and everything worked great. UPDATE: The fuse holder doesn't make a good connection. it works fine for about 2 weeks, then it fails and the system doesn't work. I remove and then screw the fuse back in and it works again. I would like to replace them if possible.
