yeah,
all corolla alternator not much different with out side bracket,
but different with rotor and stator coil...n oso regulator part number!
my stock SVT alternator oso got problem last time.
what i have done:
1)Replace only electronic regulator taken from BT model,charging same,
not much different....
2)I had try replace with stock 2E alternator(from EE90/EE80),not much
different oso but charging a bit low...
3)Lastly go n buy one 3S alternator at chop shop for only rm80,
bring to home and service(check carbon brush/diode continiuty)
after confirm all okey...i fix it...till now that alternator given good
charging to my battery almost one year!!
