I left work yesterday and was travelling along at a nice speed and I look up and see my Redline completely dark. I knew this was bad because I have it hardwired into my fuse box to come on when my vehicle starts.
I pressed the power button and it came on and said low voltage and then it turned itself off again. I did this a few times and it kept doing the same thing over and over. Finally, it stayed on and I remembered that you could set the Redline to display the vehicle's voltage.
I looked at it and it would go anywhere from 12.6 all the way down to 10 and then it would display low voltage and shut down. I just got a new battery in my vehicle so I ruled that out and I started thinking that it was the alternator even though most alternators last more than 5 years in a vehicle with less than 60k miles.
I got home and unplugged my hardwire and plugged a coily cord directly into the lighter to see if it was my Redline or my vehicle that was having issues. I drove around with my A/C on full blast, radio on, and moving my electric windows up and down to see if it would affect the Redline's voltage display. It stayed locked in at 13.5 for most of the time and it went down to 13.3 once, but then it went back to 13.5.
The good news is that it's not my Redline, battery, or my alternator. The bad news is that, for some reason, my hardwire does not supply a constant source of electricity to my Redline. I am anal when it comes to wiring up my electronics so what could be the problem?
I could understand if there was a short where the radar detector turns itself on and off when going over bumps or something. I just don't understand why the connection seems good, but the voltage goes up and down on my hardwire connection.
I have to give props to Escort for making a hell of a detector with a very useful voltage display. If I didn't have the voltage display, I would probably be going to AutoZone to have them check my battery and alternator. After seeing its usefulness, Escort should take the next step and make the Redline announce low voltage or make a beeping noise if it reaches a certain voltage so that people will know that they are not protected when it goes silently dark.
