Check the wires going to your alternator, the power cable that is held on with a 10mm nut if not tightened completely will cause this, did you have a new alternator or a refurbed unit? The how to guide will show you how to overload the alternators signal control cable and take it from 3v upto 12v, if you had a new alternator with warranty DO NOT DO THIS MODDIFICATION get the unit swapped instead
