Check the AC voltage level. DO it at the alternator output terminal. 30 millivolts AC is allowable (.030 VAC).
If more than this then you have bad rectifying diodes and the AC voltage is messing with the signals from wheel speed sensor or ABS module.
The other possibility is that rear wheel speed sensor failed or is contaminated and it is not associated with changing alternator.
