inst lights meaning night time lights or warning lights?
Warning lights, it starting happening when we had to replace the alternator, then the battery, we did this 3 times. We figured the power steering pump leakage was creating the problem. However we're not sure. Thanks for the feed-back.
go to auto zone and have them scan the codes at n/c and post them

Yes. The power steering fluid leak eventually shorts out the alternator,making all the dash lights go crazy. My 1990 ls400 is going for 3rd alternator and 2nd power steering unit.
