Title: Buzzing noise when off = dead battery
Post by: T88C on August 07, 2007, 01:30:22 AM
Now, i got the car at the end of last week so i havent driven it that much.  to get it home was about 30 mins then i drove it around for a little bit today after i got it registered.  i went to my buddys house tonight and after i got shut the car off there was a buzzing noise coming from the drivers side between the firewall and the intake manifold.  i havent been able to narrow it down cause it was dark but thats where its coming from. so i didnt think anything of it when i got out of the car but 3-4 hours later the car was dead.  got it to start by jumping it with my buddys jeep

now what is this buzzing noise ( i know its hard w/o hearing or seeing it) its on when the car is on and stays on when the car is off.  i dont know what it is? the car runs fine.  i might just have to go and start unpluggin ish tomorrow.  but if anyone has had this happen please let me know

get a piece of waterhose and use it as a stethoscope to narrow down the sound.

i have the entire assembly and i will be bringing it home. only thing is you cant buy it new anymore i think, and they are worth good good money, i mean its the WHOLE master, acumulater, everything.

You dont need the whole assembly, just a relay I think.... dont spend your money on all that stuff heh, because it wouldnt fix a THING if its the relay.

Not trying to gyp you Mr Mason but I hate when I spend a bunch of money on something and it doesnt fix anything.

soooooo i took the relays out that are under the vacuum tree to a parts store to see if i could get a replacement.  of course one of them didnt have a part number.  they did have the other relay but i wanted to be sure so i hooked both of them back up to try and pinpoint the bad relay. 
i hooked everything up and..... no noise.  i thought dead battery... nope started right up.  i let it run for a lil bit then shut it off and still no noise!!!
now the way that my luck has been going everything is prolly broken. lol 
so does anyone know which relay it is so i can go and pick up a new one?? wish me luck
