I checked the ground for the switch and found that the ground is good. In this switch the pilot light would not light without a ground. I don’t want to go to a two prong switch because I’m just plain stubborn. So I did some digging and opened up one of the faulty flashers. It seems that the thermal/mechanical flasher switches are no longer just thermal/mechanical, they also have electronic parts. The main switch to the signal lights is still just thermal/mechanical, but the part that controls the pilot light is electronic and has a resister and transistor. It seems that in this case the transistor has failed closed, feeding constant power to the pilot light. My solution is going to be to buy a couple (so I have a spare) of Wagner 550 heavy duty flashers on e-bay, these are new old stock and I think they will be strictly thermal/mechanical. Incidentally the two flashers that failed were: NAPA 550 12V 32-CP Max6 33620, and Eaton Bussman Series 12V 32-CP Max6 550 UNP.
