Not charging, no CEL or trouble codes

1996 XJ se with a 120 amp alternator upgrade. It has been running fine for a year and a half.

The alternator isn't charging, there's no CEL or stored trouble codes in the PCM

I pulled the alternator and it benchtested as good.

The battery and all the connections (checked twice), all are good, including grounds. Belt tension is good.

The Batt temp sensor has 20K ohms, the FSM says it should be 11K @ 70 but it's about 40 here now.

I'm only getting a little over 1 volt at the ASD relay terminal.
