Alternator IS 250 Psffftttt now Kaput

[MVrod]

Tonight on my way home the Lexus had a hissy fit . 

Cracking through the radio and then alternator light came on dash lit up like a Xmas tree VSC on and all warning lights , it kept running then power steering disappeared sat nav went blank and all interior mood lighting disappeared.

I managed to limp home and the car stopped it would not re-start Battery was flat .

After a few minutes the car started and all was ok.

After a few seconds the scar stumbled and the alternator light came on lifted the bonnet/hood and I could smell burning the alternator was fried.

I have removed alternator after discovering the small bracket on the back eventually and it smells quite acrid so I suspect it is toast so new one has to be found .

Will I need to have any lights reset by Lexus after replacement ? I am going for a quality aftermarket one can you recommend a make?

Can't reccomend a brand other than the OEM Denso, you may be able to get yours refurbished if it has just suffered rectifier failure for example.

with regard to any 're-setting' then you will prob only need to disconnect Battery for say 15 minutes to do a soft reset of ECU to clear any errors thrown by voltage fluctuations, But you really should disconnect Battery anyway When fitting an Altenator so this will be achieved.

You will have to 'reset' your electric Windows after Battery removal ( and moonroof if fitted) but audio equipment does not require any codes.

Also give your Battery a good long trickle charge as it would have been deeply discharged when you were using car with nothing going back into it and also to give your new Altenator a nice easy ride when first used.

I see your location is Lancashire so if you're anywhere near Preston, Ribblesdale Auto Electrics will either be able to supply an exchange or refurb your existing one for you. That sort of work is done at their Deepdale site so it's got to be worth giving them a ring on 01772 796047, or failing that, their main line number is 01772 555011.
