Currently we have a pro mag 44 and an 8168 retard box with a six shooter and an emi 8 channel timer. The problem is the motor is not retarding the timing at all. I have checked the retard box and its working fine. I have checked the emi box and it is sending signals at the right delay times. I have tried 2 six shooters now and still it does not work. Any help would be much appreciated.
