A couple weeks ago, my battery would not hold a charge. I put in a new battery and still no luck. I took it to Lexus (had no problem driving it once it was jumped) and was listening to the radio on the way down. They told me my alternator fuse was busted and I needed a new battery. I brought them a new battery (since it was under warranty) and they replaced my alternator fuse.
Things seem to be better but now my speaker is muted, my CD changer seems busted (makes some loading/clicking noises when I insert the cassette but can't select CD from the head unit), and my phone doesn't turn on at all. From searching, it seems that the phone may be affecting my radio so that is a separate issue.
When I asked my Service Advisor about everything, he sounded fishy so I wanted to know what the alternator fuse sits between. I assume that it sits between the alternator and everything else - so a blown fuse would look like a blown alternator. If this is the case, then I wouldn't have been able to drive my car down to the dealer with both a bad alternator fuse and bad battery. He also said that nothing was working when they got the car, that all of the lights were on in the dash and that my radio wasn't working. I'm not trusting anything he says and want more understanding of the system.
Right now, I'm thinking they did something to my electrical that busted the phone/radio and they are trying to hide something by saying that nothing was working when I brought it in.
Any help is greatly appreciated!
Again, a 91 LS400...
