Hello, I have a 2000 LS400 and all my gauges are dead. Radio, heat and air conditioning all work fine. One of my battery cables had come loose and after I went and tightened it down the car started fine but the gauges wouldn't light up. I'm worried I may have blown something. I read that was a somewhat common issue but I thought it was only on early LS models. Is there a fuse just associated with the gauges? It didn't appear so from looking in the owners manual. Any ideas on how I can fix this? Prior to the gauges dying they were bright and working just fine. I didn't notice any dimming or other behavior to indicate they were about to fail.
