sparky85 Posted November 3, 2018 Report Share Posted November 3, 2018 So recently i started losing power to my instrument cluster,hvac,moonroof,radio only when i hit 1500rpm in my 2008 ford edge sel in park in my driveway thus not moving. So i had my wife press the gas pedal while i had my multi meter on the battery everytime she hit the gas the voltage would reach about 21volts is this a bad alternator or is there a voltage regulator Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted November 3, 2018 Report Share Posted November 3, 2018 New alternator time, it sounds like. You could replace the regulator (in the alternator) only, but it costs almost as much as the whole alternator. Make your decision on which brand to buy based on whether you DIY or not. Although Motorcraft remains the #1 choice regardless for OEM spec'd alternators. Quote Link to comment Share on other sites More sharing options...

WWWPerfA_ZN0W Posted November 4, 2018 Report Share Posted November 4, 2018 With time & care, yes it is DIY. Yes, it is a good ole PITA too. Change belts while you are in there, old ones have to come off anyway. 2 Quote Link to comment Share on other sites More sharing options...
