my z

just got rid of the timer that keeps buzzing and making everything go dim... not sure what it is yet

everything still works

1975 datsun 280z

second fuse down from the top on the right what is this.... ???? it has been driving me nutzzzz

ok i started pulling fuses second one from the top on the right ... if your looking at it from the drivers seat... it quit... and everything still works...I have no panel what is that fuse?

yea it does a little... not bad ...it won't kill the motor ..it makes it flutter a little ... its timed every twenty seconds or so... it will buzz then stop and be fine ... the ac isnt even hooked up

its all new.. it did this with the old alt too... something is trying to kick on? its not the alt... sounds the ac trying to kick in or something

voltage is constant 12 to 15 drops off to about 3 for a second or so about every 20 seconds new batt and alt... clean conections i think its a relay?

on a side note it has a new alt.. batt.. headlights..ign switch..and no radio

Ive never seen any thing like this ... i have a 1975 280z ... runs excellent... the wiring is confusing me... it will always make a strange buzzing sound and the lights ( all of them ) will go dim ...not off...then pop back on.. get brighter and brighter then go dim for a second it does this every 20 seconds then repeats.. it does this all the time... weather the lights are on or not ..it always make a buzzing sound like a relay is trying to kick on.. then stops but it does affect the lights ...nothing else... has anyone had this problem ?
