i just finished the SR swap and relocated the battery to the trunk.... i made sure everything was grounded well... to the best of my knowledge

i sit down then before i even try to start it i look at the clock it wasn't on like it should be ??? then i tried starting the car... all that happened was the fuel pump turned on then off like it should... i tried my head lights... they turned on except they wouldn't go up or down

so i checked out the fuse box and i found that my 75 amp alternator fuse was blown... so i searched all the auto stores around and couldn't find one so i went to my local nissan dealer and bought one for $14.82

then i plug that in and it blew rite when i plugged it in ??? so i swapped the alternator with my KA24DE one ...did the pulley and all... plugged it back in ... realized i had another 75amp fuse laying around somewhere... grabbed that plugged that one in and it blew up in between my fingers

so i searched nico and found that there is one guy who had the same problem but on an rb swap ... but his car ran and mine didn't even get to yet... then i started searching everywhere else i could try on the net and found nothing

so i decided to make a thread youre words of wisdom are much appreciated thanks for any help

this diagram shows all the wiring related to 75 amp fuse. i dont know how you test without using a ton of expensive fuses. you could do continuity tests.
