"Error 2"

[BestRadarDetectors]

I have two Radar Heads. I do have the shifters connected but they are under the seat and the shifting and even receiving is turned off. I am using add fuse yes. I am using new add fuse that I used when I hooked my ALP up to it; own power circuit back when the unit was just turning off by itself few weeks ago.

We can start by eliminating common issues. If Ground is solid and the +12V is going to the Add A Fuse first try to use a different Add A Fuse. The speaker sounded like a battery operated radio when the batteries are low and its struggling to stay on.
