The generator decided to replace itself, work on the Lexus RX350 is not easy. However, with limited tools, I successfully installed the new device and the charging system returned to normal. After four months the alternator stopped charging the battery, no fuse, no battery, no wiring harness. The generator is out of order. Spent two days swapping out and replacing the alternator. very annoyed. oh and guess what - return window closed after 3 months
