My 1992 Honda accord doesn't seem to be charging right. I had the battery and the altenator checked and both checked out OK. I looked in the fusebox under the hood and there is a plug with 4 wires attached to it that seems to be burnt. I'm not sure what this is. Any help would be appreciated.

Is it the Electrical Load Detector (ELD)? If so, it may require replacing the under hood fuse box, which is expensive ($250). You may want to go salvage, if this is the problem. Have you checked for codes? See if it's throwing a Code 20.

After looking at the haynes manual I believe your answer is correct. I am no mechanic by far. Im not sure how to check codes. Can you give me a quick summary? Thank you very much.

Service Check Connector (SCC): Reading OBD-I Codes

When the Check Engine Light (CEL) is on, it will be necessary to locate the 2-pin Service Check Connector (SCC) on OBD-I (pre-1996) Hondas. It is normally located under the dash, approximately 1 inch (2.5cm) from the right kick panel. Take a small screwdriver and carefully pry it from the rubber mount. The other 3-pin connector in the rubber mount is the Data Link Connector (DLC), which should be left alone. Jump the SCC with a paper clip, turn the ignition switch to ON (Position II), and count the number of times, if any, the CEL flashes. Reference a Diagnostic Trouble Code (DTC) chart to identify the code being displayed. The SCC is also jumped, when an induction timing light is used to check engine timing.

After troubleshooting, turn the ignition switch OFF, remove the jumper wire, and reset the ECM, by removing the BACK UP (7.5 A) fuse from the under-hood fuse box for 10 seconds. Disconnecting the BACK UP fuse cancels preset radio stations and the clock setting; therefore, they will need to be reset.
