So I have a 94 prelude s n when I first bought it the head lights worked. I swapped eng trans n ecu to a h22a dohc vtec obd1 with stock p13. New engine harness from rywire. I replaced the head lights with halos n everytime I try to turn the headlights on it pops the fuses and fries the alternator. What can I do or try here to insure I dont fry my new alt!? Thanks

How do you fry an alternator from a headlight install? Hint, don't keep installing stuff that fries your alternator. They're probably seriously miswired.

To echo marc's reply, I'm betting the headlights do not have anything to do with your alternator problem.
