Today as I was driving, I started hearing my wireless unit beep as if I had just started the car. This continued and became erratic until I was only hearing a single beep occasionally. I also observed that only the power (red) led was coming on and flickering at best. I don't think the LPP is failing and that this means there's a wiring problem with the Cheetah kit but wanted to put it out there for any thoughts and feedback. I don't have a circuit tester but feel this would be the first thing to use to check connections.
