buzzing from the computer?

i just put a clutch in my 88 tc 5spd. got it back on the road and i currently have 147 break in miles on it. i just tackled an electrical problem with my no tack and speedo and some other stuff, turned out to be fuse 18 witch was a 10 amp witch i replaced with a 15 but i fixed that before i did my clutch job...and it worked and it was fine till i was doing something in the yard and i hit my switch for my head lights...car wasn't running just used the battery.. the first thing i noticed was there was a buzzing and i poped the hood and theirs a black box on the passengers side of the car just steady buzzing and vibrating slightly. how do i fix that..also my voltage regulator is bad i believe because if i start the car with just the engine running no radio lights ect the tack needle is fine. if i flip the lights switch the needle drops to 500 rpm or 0 rpm and the speedo side of the cluster inset lit up the ford green it should..its half dead lol. and if i hit the turn signal the speedo needle jumps to 15 mph each time it flashes and my high beam light goes on and its just a mess....my slave cylinder for the clutch went out today also so i have to fix that any tips or anything that might be able to fix this problem?? help!!

I used to have that too in my TC and it did it all the time. My idle would stummble a tiny bit. I never knew what that was or looked into it. But it did it for a couple seconds then stopped. Few min later it would do it again...

Sean, that black box you speak of is the intergrated relay control module, that contains four relays that run you car. You seem to have wiring problems, that you need to address.
