Thanks for the replys. I should have explained the system a little better. The system has a 3 prong heavy duty flasher and it has always been working this way from the day I installed it about 10 years ago. I have also installed a small beeper to let me know that it is on. Just thought someone might have run into this before. I have replaced the wire harness and the flasher since the inital install. Still no help. Kind of a noggen scratcher.
