Lexus SC Reduced Engine Power

Hey, I've got a 2000 Lexus SC with a gasoline engine and I'm running into a weird issue. Getting reduced engine power, a warning light on the dash, and it's starting poorly. Plus, the lights are flickering. Error memory shows something's up. I'm thinking it might be the generator, anyone seen this before?

Summary of the thread

A 2000 Lexus SC is experiencing reduced engine power, a warning light, poor starting, and flickering lights. The issue is suspected to be related to the generator. A similar problem in another vehicle was resolved by checking the serpentine belt and replacing the generator. The generator was confirmed as the cause, and replacing it resolved the issue.

Sounds familiar. Had similar symptoms with my old Volvo V70 - serpentine belt went bad and messed with the whole charging system. Check that first, but if it's not that, it could well be the generator itself. Is the battery low?

Good call on the belt, I'll check that. But say it IS the generator... what kind of damage am I looking at? Is it a case of just replacing the unit, or could it have fried other components too?

With my Volvo, just replacing the generator solved it. But honestly, get it to a workshop. A defective generator can cause more issues, like frying the starter motor or even causing engine misfires due to low voltage.

It WAS the generator. Workshop confirmed it. New generator installed for 960€. Thanks for the heads up!
