  1. '89 2.0 Si heavily vibrates at idle with headlights or hazard lights on.

    3rd Gen
    '89 2.0 Si engine load increases heavily with headlights or hazard lights on. Hi all, My 1989 Prelude Si B20A5 vibrates at idle. As in, the steering wheel visibly shakes, and the whole car vibrates as if it is under heavy load. But the RPMs do not fluctuate. I thought it might be a...
  2. (2nd Gen) Rebuilding/Upgrading Alternator

    2nd Gen
    So I've been doing some research, and before I pull the trigger on a rebuild kit, I wanted to get some other feedback. This is somewhat for performance, but primarily for my sound system. I'm not looking to have anything too crazy (at least not yet), but I'm a very nitpicky basshead and like to...
  3. Possible Electric Issue?

    5th Gen
    Hello Lately, I've been having a lot of issues lately with my 97 H22A4 Honda Prelude. It all started about 3-4 weeks ago with the beeping. Most vehicles beep when you have your door open and with the key in the ignition. Well one day I get off work, open my door and the car is beeping WITHOUT...

    Radio started turning off a few times randomly yesterday while driving. Today my car tried to start but couldn't quite manage. Battery is only a 1.5 yrs old. I tested the alternator at Autozone - it's good. While uninstalling the alternator, the wiring to the alternator was corroded to shit...
  11. alternator..

    5th Gen
    does anyone the factory output specs on our alternators? I need to upgrade for my new stereo system but cannot afford an actual "car audio alt" there like $349.00.... was wondering if a shop could beef it up, and if so how high could it go.
  12. New Alternator Low Amps?

    5th Gen
    Hi Everyone - So for those that didn't follow my fiasco with my vtec solenoid, let me go ahead and warn that my knowledge of cars is somewhere in the range of "pitiful". That being said, I have learned a hell of a lot in the last month of working on my '97 - poor thing is finally starting to...
  13. Alternator hell

    5th Gen
    Okay - I have another thread going a bit about my trials recently, but I figure this warrants its own thread. My alternator is shorting. It's killing the battery when it's not even on. Not good. So I have to pull it out. This is the one topic I have yet to find a DIY walkthrough on, so I...

    my alternator died last week so i figured i'd get something a little beefier and stumbled across one on ebay that was stated to put out 140 amps for 135$ er so shipped. the first thing i thought was that it was one of those rip offs way too good to be true things. but i figured worst thing...
