I bought my 1994 ES300 last year and I simply love this car. It has about 116K miles on it. Lately I have noticed a problem with the electrical instruments i.e sometime when I'm driving, all of a sudden all the lights, instrument panel, radio headlights just turn off for about a sec or two but the engine keeps running. I have also noticed that when I apply brakes, the headlights seem to dim a little. What could be the problem?

The second issue would be...
Bad grounds (or)
Bad alternator (or)
Bad battery.

Thanks for the reply tuan92129. I posted the same question on another Lexus forum and they also mentioned Bad Ground so I think that must be it. Hopefully it won't be expensive to fix!
