  • DENSO alternators are not only original equipment on many of the world's top production cars; they are a favorite in motorsports as well, where their light weight, high efficiency, and durability under the most demanding conditions make them the natural choice. Remanufactured DENSO alternators go through a grueling process. Stators and rectifiers are tested to 300 volts, while rotors are submitted to 600 volts, all to ensure reliable performance. Rotor slip rings are buffed to an 8 micron surface finish, with runout limited to 20 microns, minimizing brush wear and abrasion. Bearings are validated to OE standards and loaded with premium OE standard lubricants. New or remanufactured, a DENSO alternator is a quality component. Offered in versions from 40 to 160 amperes and beyond for hundreds of specific vehicle applications, all alternators meet DENSO's rigorous First Time Fit standards. Contemporary cars employ dozens of sophisticated electronic systems from bumper to bumper, placing heavy demands on the charging system. The alternator is no place to cut corners. DENSO First Time Fit alternators meet or exceed all manufacturer standards, mount properly with a minimum of installation issues, and provide years of reliable service. Features. Premium cores and precise OE assembly benchmarks; Design to meet the grueling heat and electrical requirements; First Time Fit provides perfect mounting with no belt/pulley alignment issues; Benefits. Service professionals preferred DENSO's alternators for a trouble free solution; OE quality fit, appearance, and durability; Full compatibility with sensitive electronics systems; Compact and lightweight design

Alternator/voltage regulator malfunction on 1997 Lexus

Showing 5 out of 5 Posts
Question From ADISINGH on Alternator/voltage regulator malfunction on 1997 Lexus

I have a 1997 Lexus ES300 6cylinder Engine
I had my alternator/voltage regulator tested at AutoZone while in the car. The test indicated that the Voltage regulator was malfunctioning. I put in a new alternator/voltage regulator and had it tested again. The test still said the voltage regulator was malfunctioning. I took the old alternator/voltage regulator into the store for a test. It passed. Do I have a wiring problem? The battery tested okay.

Response From Discretesignals Top Rated Answer

How is the regulator failing? Is it over charging, undercharging, or not charging at all? Battery light on? What is the voltage at the alternator output lug with the engine running? What is the voltage at the battery terminals with the engine running? Have you made sure the battery is fully charged and checks good? Are your battery connections clean and tight?

Need some data please.

Response From ADISINGH

The voltage regulator is undercharging . The voltage of the battery when the engine is running is 12.8 volts. Is it possible that a loose or worn belt is causing the problem? Or corrosion on terminals and or wires?

Response From Discretesignals

Anything is possible. Check the belt tension. If good, check the voltage at the output lug of the alternator.

Does the charge warning light come on in the dash when you turn the ignition on with the engine off?

Response From ADISINGH

i FINALLY HAD TIME TO THOROUGHLY CLEAN ALL OF THE POSTS AND CLAMPS AND CONNECTORS ON THE BATTERY AND WIRES. I HAD THE ALTERNATOR/VOLTAGE REGULATOR TESTED AND EVERYTHING WAS NORMAL. HURRAH

Need Help with a 1992 lexus es300 Alternator

Showing 5 out of 5 Posts
Question From joshua102888 on Need Help with a 1992 lexus es300 Alternator

I have a 1992 lexus es300, i was driving it yesterday and i simply rolled down the window and out of nowhere the battery light comes on. I quickly drive it to my mechanic, on the way there whenever i was sitting at idle at a stop light the car would act as if it were going to shut off, i put it in neutral and gassed it up to keep the car alive. Brought it to my mechanic, he says its the alternator...he fixes it, puts a new alternator in. So as im leaving i roll down the window again, and just as i suspected the battery light came on again. he put in a new alternator today, and i told him about the window problem, he tests it drives it around everything was fine, i got in the car ready to leave but one more time i rolled down the passenger side window, and the battery light comes on again. He doesnt know what keeps frying the alternator...has anyone experienced this problem before? or does anyone know whats going on, im covered for a 2 year warranty for the alternator, but it gets annoying to keep going back..Thanks!

Folks are here - relax! It can take a while to check out the zillion posts that come by.

No solid ideas for you from me. It seems like the alternator(s) are the problem themselves. The only connection I can think of is that the PW does use a fair amount of juice and if a new alternator is put in a near dead battery it's working so hard just to restore the charge in the battery (subject of a problem with it too) with any added load on it, it burns it up.

Your first post indicated the battery was low enough to begin making the engine run improperly which could have been the alternator to begin with but that battery was run down and they don't hold full amps alone all that long with needed electric fuel pump, and assorted electronics for ignition when not helped along by the alternator.

When alternator is a problem or a low battery a problem for any reason it should have the battery charged up and checked before asking the alt to do all the work at once. Battery and Alt work as a team and either one can hurt the other. Just a thought as to why this could happen,

thanks for the response, my mechanic put a new battery and alternator in yesterday. He thinks its a short, but doesnt have a clue were to begin looking, others think its a power window relay.

just wanted everyone to know that i solved the problem, seems as though the wiring wasnt right, everything was being sent to the alternator and fuse box in the engine...re-wired and now everythings great. Thanks!

Question From mainogre on 1991 Lexus LS 400 Warning Lights when accelerating

hi, I own a 1991 Lexus LS 400. When i accelerate every warning light turns on (oil, battery, traction control, coolant, e-brake, engine). When i decelerate they all turn off. When idling they are all off. Only when i accelerate is when they turn on or at high speeds of 50mph+. I did just replace the battery about 1 month ago. Any help would be greatly appreciated.

Response From speed

have the codes read at your local parts store, autozone, advanced auto, o'rileys, they will be able to scan the engine codes. you also may watn to think about just takin it to a reputable shop to begin with, this is a difficult thing to diagnose over the internet and not actually being there

Response From Tom Greenleaf

Just a thought on this - check all engine to body grounds especially with the battery replacement one or more could have been disturbed?

Well the morning after I posted the original message, i went to start my car and it was dead........ Last night I noticed there was battery acid dust around the positive connector. I cleaned it off, then jumped my car. I drove the car for about 7 miles with no problems (no warning lights and car ran fine, it didn't want to die). I even sat in a McDonalds drive-thru for 10 minutes at idle. I parked it at home and went to bed. In the morning, the car was completely dead........ Since my car wasn't dying on the road while driving it, wouldn't that mean I have a bad battery? Thanks for the help.

Response From Tom Greenleaf

You'll have to test the battery out AFTER charging it. This going dead is killing it. Check what may have been damaged by battery acid and replace the corroded cable then check it out. May have a drain going on too which is also hard on battery and charging system,

Response From mainogre

thanks I'll give it a try and let ya know within the next few days.

BTW what causes a battery drain anyways? a loose connection?

Response From Tom Greenleaf

Battery drain could be lots of things like a short of something or something is staying on that shouldn't like even a glove box or trunk light. In that your symptoms were when accelerating when engine would tilt a bit normally on it's mounts and now the corroded battery terminal something is up IMO.

When a regular lead-acid battery is low the chance of spitting acid around is up there and wiring of things near that would need inspecting. That load on the alternator to charge it back up even if enough amps left to start is hard on both battery and alternator. You can end up needing both and power surges can wreck control modules which you don't want either.

Just recently (retired long time now) jumped a family vehicle with interior lights that had been left on so dead as a door nail. Left my vehicle and the dead one hooked up so both were charging a hopelessly dead battery but got it going and 20 minutes later stopped as both alternators were red hot. Just by feel couldn't keep a hand on either and don't get hurt by moving parts if you try that. Got that car to my shop to charge with charger instead of letting alternators do it and so far so good that neither burned anything out.

If you don't have or get even a floating low amp battery charger ~$21 or so AND there's a simple device that just gives you exact digital voltage that just pushes into any cig lighter or power port - neat as you can see the real voltage and how much it drops when an item is turned on. I like that better than trusting a gauge and for vehicles with just a warning light it can give you advance warning of a problem. Cool gadget for the ~$12 bucks!

Not everything for basic care costs that much and you can use it again on another.

In that you think battery should be good (sometimes they get dropped in handling and rendered NG) before you got it you may need some added testing and can short inside and self drain by themselves.

Some may need some help to determine that or a parasitic draw/drain elsewhere,

Response From mainogre

hey tom thanks for all the help. So today i had the battery tested and it came back ok. i bought one of those cigarette lighter voltage meter things and hooked up my charged battery and turned the car on. The voltage was way too high. 17.5v. so would that mean my alternator is stuck on? ive also heard that it could mean that the voltage regulator needs to be replaced. i know some regulators are built inside the alternator and some are on the outside. if it were on the outside i would like i could fix that? thanks again.

New alternator

Response From Tom Greenleaf Top Rated Answer

I'm tired - sorry but if you see 17.5 volts your alternator is NOT regulated and will cause damage to about anything in this car,
