battery drains

[RatBoy3o5]

hey guys, another problem with the z.. the battery drains and i cant figure out from where. i did alittle trick with the test light and it shows theres a problem with either the main blue fusible link or the LTG fusible. that ltg fusible goes to the fuses by the fuel filter and it controls the horn and both headlamps. i changed the wires and still the light stays on on the test light. it dims when all 3 fuses are out but turns bright when one is connected. i then followed the blue main fuse link by cutting the whole harness and found 2 possible wires the dims the test light when cut. one leads to the alternator harness. the other goes into the fuse under the dashboard and disappears from there. any suggestion on where the wire goes to or any possible drains that can come from the z? and on the same note, my alternator harness fried. i changed it and everything works except the rpms. .. any thought on that? im just stuck and exhausted on this car
