96 Mustang GT Vert....recently installed a new alternator a month ago and yesterday went out and noticed my lights flashing as if the alarm went off...tried shutting them off now the lights wont stop flickering even when the car is running/off..hear a tickering/clicking sound comming from the driverside rear wheel well when driving or when lights are flickering. Lights shut off when I turn the key in the drivers door to unlock so I am thinking its a bad ground. If someone could lead me to where the PATS ground or anything that would cause the anti-theft lights to keep flickering I would greatly appreciate it....
