ok I have a 89 z24 with the digtal dash. I was riding along the other night and the cluster just goes out. I found a blown fuse. I replaced it and everything was ok until I turn my light back on and I heard a pop and the cluster goes out again. I check the fuse but it is ok. so now when I turn my head lights on I can not see the cluster. but if I turn the head lights off the cluster comes back on. So now at night I have to turn my lights off to see how fast im going. I have replaced the cluster but that was not it. anyone with the same problem or know what in the hell it is.
