Yeah coarse you have. A trained sparky would no that a tilt sensor could not possible pull a .6 amp drain. I don't mean fact in that sence. it means False Alarm Contol and Test but i guess you already new that as you've got 10 years experiance. All installers that sl4g off clifford generally can't fit it properly or they won't give you a dealership. As a VSIB/MESF CAT5 Cliford,Cobra,Tracker approved installer and trained auto electrician i would put clifford above all the other brands. Aint arguing with you any more go back to the office job and push some paper and leave the electrical stuff to an electrician
