MaroonDuneDoom Posted February 28, 2004 Share Posted February 28, 2004 the oddest thing is hapening to my soob. it will run showing 18volts most of the time. when i idle down, it will run the normal 14 or so. the headlights also dim when i slow to idle. when i wrap the engine up, the voltmeter climbs up to 18 or so. this short wherever has caused both of my headlights to go out, high and low beam. what is causing this. it has to be in the alternator circuit. by the way. what number fuse would my headlights be. i lost the cover and am now clueless. if somone could count for me, like reading a book left to right, i'd really appreciate it. have to go to work in a couple of hours and don't get off 'til 1 AM. thanks in advance Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted February 28, 2004 Share Posted February 28, 2004 The VR is inside the alt, so if it's bad, then time for a new alt. The dash guages are notoriously inaccurate, so get a multimeter out, and do a real test. Also tes for AC comming off the alt, as this is a good indication the VR is going out (bad diod's cause AC...). GD Quote Link to comment Share on other sites More sharing options...
Snowman Posted February 28, 2004 Share Posted February 28, 2004 Yeah, time for a new VR. I'd just grab an alternator from a junked car. Quote Link to comment Share on other sites More sharing options...

torxxx Posted February 28, 2004 Share Posted February 28, 2004 yes you can overcharge your battery and it messes with other things in your car because its charging so high Quote Link to comment Share on other sites More sharing options...

Snowman Posted February 28, 2004 Share Posted February 28, 2004 YES! Don't run it like that unless it is a life or death situation! 18volts will (not appropriate for a family-oriented forum) up. Quote Link to comment Share on other sites More sharing options...
MaroonDuneDoom Posted February 28, 2004 Author Share Posted February 28, 2004 i'm still a little hazy here. how would the voltage regulator affect my headlights dimming? also, does anyone have some spare time/energy that they would want to check on those fuses for me? thanks again Quote Link to comment Share on other sites More sharing options...
Snowman Posted February 28, 2004 Share Posted February 28, 2004 The voltage regulator can cause your headlights to dim by reducing the voltage available. Simple. Quote Link to comment Share on other sites More sharing options...
torxxx Posted February 28, 2004 Share Posted February 28, 2004 If you are charging at 18 Volts. Your VR is blown a 12 volt car is a 12 volt car not 18 volt Quote Link to comment Share on other sites More sharing options...
