1990 Honda Civic Question: fuse pops all the time

You said the fuse keeps blowing. Does it blow immediately? You will have to isolate the circuits to see which circuit is causing the fuse to blowing. Fuse 1 supplies power to the seat belt control unit, seat belt reminder on instrument panel, time clock, and reverse lights.
Disconnect the reverse light switch on the gearbox (it is a two wire connection one of the wires is yellow) the reverse light switch should have no continuity across the switch in any gear or nuetral. The time clock isn't likely to be the problem. The seat belt system is most likely to be the offending member! The control unit for the seat belts is behind the radio behind the center console Honda is good about labeling the computers (so it will probably have a label on it identifying it as the seat belt control unit). I've seen the wiring harness frey and rake wires within the wiring harness above the left foot well area where the wires go into the door causing the fuses to blow.
with the key on reverse lights disconnected, wiggle the wiring harness one section at a time and see if the fuse blows. If the fuse only blows once a week it may be more difficult to isolate the problem.
