    My TR stalled a few times yesterday when coming up to a traffic light. was able to reporcude 100% of the time when the radiator fans were running and when the ac was on.

    I have the SR fusebox mod done. Connector are intact. New battery last year

    I suspect there is too much workload for the arthritic electrical system

    Anyone else have similar especially after the fusebox mod?

    I'd be more suspicious that your idle RPM is just set too low (or imbalanced). A reference from one the Pros who posts here that he targets the higher end of the warm idle RPM spec (with fans off and AC off):

    presumably to help when the fans and AC are on. I'd also add that my tach isn't too accurate (an actual 1000 RPM as measured by using a frequency counter on the RPM flywheel sensor signal reads ~1150 RPM at the tach needle).
