Guest vanir97 Posted April 26, 2006 Share Posted April 26, 2006 Mt amp gauge is starting to bounce all over. from the looks of it the Hitachi alternator is original to the car. Where is the number located on the housing, and what is the AMP rating of this unit as it is orignal to the car. I am running an electric fan/fuel pump and until I accidentally shorted the positive post on the alternator (stupid screwdriver) amp gauge was rock steady with no flutter. Now it flutters but steadies a bit when fan goes on. Quote Link to comment Share on other sites More sharing options...
BobsZTwins Posted April 29, 2006 Share Posted April 29, 2006 You didn't mention what car this is on. Since you've got an Amp meter I'm guessing it's a 240 or 260 since the 280's got volt meters. Those are mainly 35 amp alternators with external regulators. Sounds like you may have damaged the regulator. With an electric fan and fuel pump you're probably stressing that poor thing out! I upgraded to an internally regulated unit on my 240 and a 100 amp GM unit on my V8 260. I replaced the Amp meters on both cars with Volt meters from 280s, much safer! Amp meters can be a fire hazard since the full load is running to and from the meter in the dash. Quote Link to comment Share on other sites More sharing options...
