For those of you that do not have a multi-meter, I would suggest you pick up one. There are some links a few pages back in this thread on where to get them very inexpensively. I have heard harbor freight has them for a good price, and I think the link on this thread was on ebay. You should expect to pay anywhere from about $7 to around $20.
