Question about 2000 Lexus ES 300

1 Answer

I have a discharge warning light on in my car. The car will start and run for a while (on a charged battery) but it soon powers down (dash and cabin lights dim to almost zero) and the car shuts off.

The alternator and starter are about 10 months old, and the battery is about 8 months old. I took the battery out put it on a trickle charge, cleaned the terminals, checked the fuses and checked wires to and from the battery and the alternator for any obvious damage. I then hooked the battery back up and started the car, letting run for about 1 hr until it shut itself down.

Alternator or associated wiring suspect... test for 14.4 volts at battery when all is hooked up proper and running.. if less replace alternator or diagnose further the wiring to and from alternator

Posted on Dec 01, 2014

Testimonial: "Thanks milespeed. The battery is running proper voltage when it is all hooked up, so it looks like alternator is the issue. The thing that is still confusing me is that I am able toget a voltage reading from my alternator as well, so it makes me think the wiring is no good."

After starting transmission won't move out of park


It sounds like if this is a car with the brake interlock, meaning the car will not shift from park unless the brake is pressed, there is a malfunction there, some are electronic and it may not be getting power to it especially if there are other warning lights on the dash. It would help if you could give more details, like which lights are on. Most cars with a mechanical interlock will have a cable you can adjust either at the brake cable or at the shifter.

Alternator light came on all of a sudden then all lights on dash came on and car wouldn't start after that


Maybe your battery is discharged - did you check that out? Alternator warnings are there to let you know that the charging circuit is not working. And when that happens batteries discharge, and car will not start!

2002 toyota prius warning light - car with exclamation mark


The light that looks like a car with an exclamation mark in the middle of it is the HYBRID WARNING light (see diagram below) You must scn the onboard computer network to determine why this light is coming on. You also need to scan your computer system to find out why the engine keeps dying. If the hybrid batteries are discharged, they must be properly recharged to prevent serious damage.

CAUTION: Read ALL service and warning lables in the engine compartment before attempting ANY type of service on a hybrid vehicle. The wiring harnesses that have ORANGE connectors are HIGH VOLTAGE connectors and can cause serious injury or death.

DO NOT touch any wiring harness or component that has a HIGH VOLTAGE warning label on it.

My recommendation is to tow the vehicle to a qualified hybrid repair center (preferably the dealer) and get it properly diagnosed and repaired. The high-tech, high voltage systems in this vehicle is nothing for anyone but a trained, certified technician to be messing with.

88 Izusu Trooper II with 274000 miles Battery warning light comes on when first starting and running- after driving awhile, it goes off and starts charging- also during the warning period- the blower


Sounds like your battery isn't charging properly, first thing to check, is your alternator belt slipping, is it tight enough, if so does it need replacing?

Next the battery, if its over 2 years old it could be on its way out. Does it hold its charge?

Finally, Alternator, is it still providing a charge for the battery? Are all electrical connections good and clean?

It sounds like your alternator is bad. East way to confirm, take it to local auto parts store (IE: Autozone, Advance, etc) and have them do a FREE charging system test. Couple of thoughts; you have two new batteries and your poor alternator has to work twice as hard. After you put new batteries in, you've been running on straight battery power. Alternator normally runs all your electronics and recharges battery(s) but if Alt has gone "south" then you're on straight battery power.

All warning lights & dials on dash flip on and off continuiously?


I would suspect that the alternator is not charging sufficiently.

Be sure that it is charging or you risk a break down if the battery dies.

Car won't start


Your battery is discharged. Jump start the thing and leave it running for a bit (outside, of course) to re-charge the battery. Check the interior lights, etc. because someone probably left an overhead light or something like that on.

The battery has discharged enough such that it will not start the car, but not enough such that it will not light up the little ***** light bulbs on the dash, etc.
