Hello. Welcome to Just Answer. Please allow me to assist you. A local garage can check this, if they have an alternator/charging system test tool. The test tool needs to be able to detect the voltage output of the alternator (should be around 14.4 volts DC, and, it needs to be able to measure the amperage output of the alternator (at least 50, higher is better). If either value is below specification (which I would suspect will be found), replace the alternator. Note, the alternator test will pass if the lights you speak of are not illuminated. I suspect you have an internal issue inside the alternator which is intermittent. Personally, based on your explanation of the issue, and experience with this same problem in the shop, I would replace the alternator. When choosing an alternator, there is no substitute for a Toyota part. Low-cost parts store alternators have horrible quality issues and should be avoided unless absolutely necessary. If you have any questions, please feel free to reply. Please confirm you have received my input. Thanks.
