They have ground kits available that make your grounds much better , and are supposed to make your electrical system and battery last longer.I just bought one , it has 5 ground wires , and a voltage regulator that goes on it to prevent spikes.It wasn't very expensive , only 20 bucks.It should be here early next week, so I'll be able to give a report on how well it works. <img src="/forums/images/graemlins/kewl.gif" alt="" />
