I'm trying to help my son find a rectifier for a 24 V alternator. The alternator part number is 27030-56150 (Nippondenso # 100210-2290).
We would usually use Partsouq for exploded diagrams to identify the rectifier number and then start a search for suitable parts from there.
But this Toyota part number does not show up searching any of the parts sites that we have used in the past.
Does anyone have a lead for where to get info for this alternator? So that we can try to source a rectifier? Photos of the nameplate follow for reference.
Also, does anyone know what the numbers reference at the bottom left of the namplate?
I'm still digging for information on the interweb, but seem to just hit all roadblocks.

- stumped - 😕

I would try to find an alternator rebuild shop that specialized in this field and maybe they can provide if not something original, an aftermarket rectifier. It just needs to convert the AC to DC, albeit 24+ volts. Someone has to have something that will work. Maybe try a shop that also does large truck alternators... I really wish both you and your son the best of luck in this search!

Yes; we had a shop confirm that the rectifier was the problem. It's a guy we have used several times previously. He has resources for parts but was unable to identify a replacement rectifier, so that's why I turned to the MUD world. Lots of guidance in the past has me hoping that there is someone with a helpful nugget of knowledge.
We have a replacement Chinese alternator, but just don't feel comfortable without a backup. Thanks
Oh and it's for theglobb's Red Rocket Troopy - we are trying to get the kinks ironed out of his ISUZU 4BD1T swap.
 
Delco Remy seems to think that their Pn DA4856 is a replacement for Toyota 27020-56180 as well as 27030-56150 which leads me to believe that the two Toyota parts are similar.

27020-56180 shows up in the Toyota documentation so parts for it might be what you are looking for.

For his specific vehicle, Partsouq has 3 alternator part numbers, 27020-56180 being one of those. The others are 27020-56110 and 27060-58090.
There are 2 rectifier part numbers, but we don't know which rectifier goes with which alternator. Numbers are 27357-54190 and 27357-63020.
We know the 27357-63020 does not match with what is in the alternator we have (27030-56150).
We haven't found much info on the 27357-54190 rectifier. On parts sites, it is either out of stock or prices reported of hundreds of dollars. He can buy a couple of knock-off alternators for that price, rather than a rectifier to repair this one - if it is the correct part number.
So now we will look for an aftermarket rectifier for 27357-54190.
Again, there are full aftermarket alternators available; we were just hoping to repair the Toyoto unit.
