On a little side note, there's been some debate on whether or not caps are a good thing, or if they do more harm than good. I can see both sides, but just remember that if your electrical system is already struggling then putting another strain on it like a cap may not help much. However, if it needs just a little boost, then a cap could be the answer. I could tell you a story about caps in a minitruck I use to have, but I don't want to bore anyone anymore than necessary.
