i need to knw where to start on 1990 Honda Accord

honda dealership they said the fuse blow when they start the car i need to re Wire the electric system

Asked by for the 1990 Honda Accord
Which fuse blew? What system was affected? Do you really need an entirely new wiring harness?

Autozone does have repair guides free online for many makes/models of vehicles. I have used it with some success since they often provide wiring diagrams. Most auto parts stores carry Haynes manuals but you might be able to find a factory service manual for your Accord on ebay.
