    Default 1990 Honda Accord charging problem

    Have a 1990 Accord EX 210,000 mi. Battery light came on, took battery
    and alternator to A-Z for check, Battery was bad, alternator said
    good. Put in new battery and battery light came on a few miles later.
    Battery voltage 12.54 with car off, 12.28 when running. Replaced
    alternator, same results. Looks like alternator is not kicking on for
    some reason? HELP?

    Too bad you swapped the alternator. Usually you can just slip in a new
    set of brushes into a Honda alternator without even removing the unit.
    They probably charged a ton of labor to get that sucker out, right?
    Now it's hard to know if the 'new' alternator is the real problem. Do
    you suspect they don't have a clue?

    I replaced the alternator, it wasn't really that hard. AutoZone did
    check the original and said that it was good so I stuck it back in
    along with a new battery. When the battery light came back on I
    figured that maybe the alternator was intermittently bad? because
    there was only 12.5 volts. So I replace it. Light is still on and new
    alternator doesn't seem to be charging either.
    Dash Fuse #2 is good.
    Alt plug black/yellow wire to ground with ignition on shows 12.5v,
    also green/white to ground
    Battery light not on with alt plug disconnected
    Battery light comes on when jumper white/blue wire to ground

    I must be overlooking something simple?

    depends on the alternator - on the civics, the mitsubishi brushes are
    not replaceable.

    Just tried that and still does not charge! Where is the ELD anyway?

    Thanks for the info.
