Electrical problems with S13

[Starclassicbb]

Hey! Im currently working on my 89 S13 n i got a Kade engine in, i did the wiring as well matching colors you know from the ECU to dash but before i got all the Dual cam stuffs i tried to crank my previous single cam KA but for some reason it burn all my grounds just grounds So main ground was from altenator i guess the altenator was bad or something!! Soo i decided to go KA24DE everything its connected right now i dont have an altenator on the motor but heres are the following problems!! I hope someone here knows wats going on!!!

- everytime i put the key in "switch" the radio keeps turning OFF & ON i checked all the radio harness wiring was same as i had it when the car was running perfect

- my EGI relay makes a bussing sound and it wont stop until i disconnected the batterie cable It only starts when i have the radio on or it stops when i close my door

- all the lighing looks weak (so obiously the battery its almost drain)

-everytime i turn the "Hazard switch" ON the dom light blinks allown with harzard switch. I dont think thats normal i dont remember seen that when the car was straight!!

-all my fuses are good!

-my lower harness its not connected but i retaped just where it was burn. people keep telling just to replace it but i checked the fuses box but there are no signs of any burn damages its was just 3 Ground that were smoking n got burn The one thay comes from the altenator was really bad!!

so far that's are the only problems the electrical system its giving me right now!! Remember i dont have the lower harness connected
To fuse boxes i dont have the altenator on but it keeps doing all that.. ANYONE !!??
