ok so im working on a 92 prelude that has an f22b jdm swap in it and i had it up and running untill i relized that the car wasnt charging because the wire to the alternator was semi loose and wasnt making a good connection. i turned off the car went to try to start it and i had 0 power for some reason. The only things that work on the car are the horn and the hazzards absolutely nothing else that is power works.

Is this a main relay issue or what the eff is going on. it was just running just fine and turned it off and now nothing. im stumped at this point thats why i decided to get on here and see if i could get an answer. i have googled it but found nothing.

 

check the fuses under your hood

 

92-96 are all 4th gen, so....

Check out electrical diagram (attached). On page 2, The horn is on the top part of the diagram. What sticks out to me is fuse no. 32. It is 100amps and probably a breaker, but if it is out, the alternator would be able to keep the car running, but once turned off, everything below that fuse would be inoperative.

 

yup 100 amp fuse done for. tested it with my dmm but read fine but then i looked at it and it was burnt up. i have another problem too. i ordered a brake switch hoping to fix the fact that my rear brake lights do not work and my brake lamp light comes on as soon as i touch the brake pedal. running lights work fine just not the brake lights.
