1990 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? |

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?? |
