The previous owner of my previa did an awesome job of keep record, I mean it was something I never had experience with older cars.
But there was never a receipt for alternator change or starter change. Both are currently functioning properly and no issues.
Since I've been itching to get things changed out, preventative maint mentality, I decided to go with these parts.
To be honest, I never had issues with going to the local parts stores and buying remanufactured items. The issue is, I never questioned the quality of these parts. I just assumed they were good.
After jumping on Toyotavantech, Tim who is an "OEM parts nazi" showed pictures of a reman alternator. The issues were the diodes were soldered poorly and the quality looked like crap, and eventually failed. He took it apart and took pictures. I never had this issue, but it does make me more mindful of parts. Here is the link

"If you look closely you can see several of the diode stems have desoldered themselves from the assembly. This is partly due to a low temp solder the rebuilder improperly used and partly due to the alternator being overworked (owner tried to use it to recharge a dead battery). I don't have a factory Denso diode assembly handy for pictures, but those are identifiable by a gray plastic coating Denso uses to protect from moisture. Even if your diode assembly looks good it doesn't mean it is. There are several diodes here but it only takes one to fail and you're dead in the water. Sometimes diodes short. A shorted diode will allow electricity to travel both ways. An alternator with a shorted diode will often still charge okay but will also discharge when not in use. The easiest way to test for this is before you remove the alternator. Go to the little plastic "+" box (under & slightly forward of your air intake tube) & open it up."
His mentioned that Denso remanufactured alternators were not reman by Denso, so that was the issue. So when I looked for an alternator, I went with one that was rebuilt by Denso.
Which has this seal on top!
