I was wondering if anyone knew the current draw of a DEI radar sensor (508D) and a motion/tilt sensor (507T)? I have them both sensors wired up to the GND when armed pin of my 790XV and it's only rated for 500mA. I'm wondering if I'm overloading the GND when armed pin and that's why my sensors are acting so funny.

Did you diode isolate the orange wire on your 790XV?

Yep, I did put a diode on the orange wire after I got a copy of the 790XV install manual. This is how I put it in:

The weird thing is the motion/tilt sensor keeps giving random false alarms and now I can't get the radar sensor to produce a warn away signal even with the sensativity turned all the way up. I checked the power and grounds to the sensors and they all seem to work correctly, 0V unarmed and 12V armed. My only guess is that I'm overloading the GND when armed pin since it can only source 500mA and this site says relays use about 200mA, so that's taken by my starter kill relay. I'm wondering if the 508D and 507T sensors need more than 300mA?
