What sensor/controller should i check to replace.

Asked by Nov 19, 2016 at 11:27 PM about the 2000 Lexus ES 300 Base

Question type: Maintenance & Repair

Good battery, new starter, no issues prior. Next day nothing, no clicks.
Battery at 1.28v. I put in a good battery(12.56V). Interior lights and dash
lights come on. Step on the brake and lights go dim on the dash. No start,
and cannot shift into neutral. Dash lights come back on after a minute or so.
Battery positive cable is hot and battery voltage has dropped to 10 volts
after about 20 minutes of attempting to tighten cables, clean posts, shift into
neutral. After disconnecting and reconnecting power, i hear a light noise
similar to a blower motor near passanger side firewall for about 20 seconds
and then quit.

10 volts at the battery is essentially dead. I would charge the battery and maybe also have it load tested to see if it is really any good.

Battery was 12.56 volts when I started.
