Just finished my instal of Blinder M27 and Cheetah wireless system. Ocasionsionally I will notice the green light will go out for a second then come back on. It is very random. I could go 10 min without it happening or 2 min. The car is a BMW 328 i. I used the power node because, although the batteries in back there are two terminals in the engine compartment that are hot all the time, not just when you turn the car on. When that green light goes out, am I unprotected?
