Rated 1 out of 5 by 1 reviewer.
Rated 1 out of 5 by Junk It literally did nothing. I hooked up to my meter and found that the only thing it did was act as an rf choke which is good if your cables are not shielded. It fell apart after 2 days and the connections we're soldered. Save your money or just run another ground strap from your alternator. July 1, 2016
