ABS light on and no speedometer or odometer

My ABS light is on all the time as well as nm the speedometer and odometer not working either. I have tried tracking this down but so far the problem is still escaping me. I have fixed the recall on the sensor under the brake reservoir l, replaced the VSS, done the test of the WSS found on the website (also hooked up an obd2 scanner and I am getting vehicle speed displayed on the scanner as I drive), checked all the fuses normally associated with these issues and all are good. A few other notes, when I replaced the sensor under the brake reservoir everything seemed to work for a minute until we test drove and it shut off again. I have a coworker who had a better scan tool and we found the ABS was switched off but did not have time to see what codes were stored. Another thing is this all seemed to happen when an alternator was replaced l, it is charging around 14.9 volts could this be a problem or could it be coincidental? Any ideas on what steps I can take next would be greatly appreciated.
