A bad alternator WILL light up the battery icon on the dash.

Well.... After the car started up just fine for me on Saturday when I had planned to troubleshoot, I decided to drive it to work on Monday. Started right up with no problem throughout the whole day (~ 4 starts total). However, on Tuesday morning it was a no-go again(no solenoid action). So hopped in my other Lexus and drove to work while thanking God my wife and I didn't get stuck at work on Monday (~65 mile away from home).
Again, I'll have to wait until the weekend to run some test. No time during the week with my work commute.
Stay tuned....

Haven't read through this whole thread but to me it sounds like the push button is going out. There used to be a service bulletin on them.

It lit up EVERYTHING + an alarm beep. Want to ask how I know that? LOL

LMAO worker! That's a multitasking FAIL, hence why I didn't include that .

Doesn't the car say "low battery, charge" on the LED? Or doesn't the battery light stay lit if your car's too low of voltage?

Not saying I disagree, I just haven't ran into bad battery notification on the car yet. Whenever my batteries take dumps on me, it's just DEAD, car will tick a few times then stop. In some scenarios it'd have a weak try at a start, then fall on its face. [I h8 the Lexus batt, changed out 4 times in half yr's ownership].

Interesting, I didn't think of this. Never figured the push button would go out lol!

The battery had an indicator on it, one of those blue/red=good kind of indicator. When my car wasn't starting, all the electronic worked and not showing any sign of weak battery.
