black thing in the driver's front corner by the battery that the air filter
box is attached to. There is even a fault code for "alternator field
circuit open or shorted" which is code 41 IIRC, Allpar's site would tell for

It's about the same as on my Yotas. I rebuilt the one in my '85

They're all about the same, but the Toyota version cracked open like an
