I'm using a Crimestopper RS7 with an EVO-ALL. Installation was working for a few weeks, then stopped. Now, when inserting the Data-Link connector while holding the button, no LED's light. When disconnected, the Crimestopper is putting out 12.0 Volts on the red wire, and 3.6 Volts on both the white and blue. After connecting to the EVO-ALL, the 12.0 Volts drops to 0.8.
So I hooked up this EVO-ALL in a different vehicle with the same setup (Crimestopper RS7), The same voltage drop occured, with no LED's. In this different vechicle, I then replaced its original EVO-ALl, and everything worked again. So I assumed I had a bad EVO-ALL.
Fast forward to today . . . I have a different EVO-ALL that I plugged in. But the same problem with no LED's. Any suggestions?
