Note:
Signs that your regulator needs replacing:
Depending on the location of the regulator rectifier, the part can easily overheat. Other causes for a dead regulator rectifier center on the battery. Ground connections are important for good voltage, and if there is a faulty voltage, the regulator rectifier can run hot. Bad grounding, corroded battery connection and poor or loose battery connections will cause faulty voltage too.

There are generally two ways for the regulator rectifier to fail:
The first deals with diode burnout, resulting in battery drain. It is easy to assume that the issue is a bad battery because of symptoms such as dimming headlights and poor starts. Checking the voltage with a voltmeter versus relying on symptoms alone will prove highly beneficial. If the voltage drops below 13 volts, the motorcycle will begin to drain the battery and eventually the engine will stop. Check for bad connections and corrosion; these can also cause voltage issues.
The other failure type is shunt regulator burnout, where the regulator rectifier fails to control the voltage, resulting in battery overcharge. Again, a voltmeter will be useful for diagnosis. Though generally, readings above 17 volts mean the regulator rectifier is not converting the excess power correctly and all of that excess voltage may cause the headlights to become extremely bright and then blow.

MUST READ - Biblical Perspective of Sex and Relationships, Great Book For Late Teens
Format: Hardcover
This book gives a right on Biblical perspective of dating, relationships, sex and more. Every Christian parent should buy this for their older teenage kids. I bought this book for my 18 year old daughter. She took it to school and found out that several of her friends had heard about the author and were also reading it. Her boyfriend is reading it now too. The Q&A portion at the end of the book is so good.

Incredible tool for engaged couples!!!
Format: Hardcover
When I ordered this I had no idea whether it would be good or not but I was just trying to find a nice devotional or something for my fiancé and I to study together. We are maybe halfway through the book now and it has been incredible. I read the first few pages as we were driving together on a road trip and I almost started crying from the special way it presented the beauty of marriage. Every chapter opens up deep conversations between us; the discussion questions get exactly to the heart of the toughest topics to broach. This book leaves no stone unturned, continually challenging you to share your hearts, your thoughts, your hopes, and your expectations with each other, while keeping God as the center focus. The author comes alongside as you let down walls between each other, acknowledging just how difficult, but also freeing, it can be to let another person completely into every aspect of your life. This book has been and will continue to be an invaluable tool for us!
