Hi everyone,

I have a technical issue that I wanted to ask about regarding a Code 3 Z3 system.

I currently have a Code 3 Z3 system installed in my 2005 CVPI along with lighting. It has worked great for the past year, however since yesterday I’ve been having a problem with the lights that I have hooked up not turning on.

The siren tones work and so does the control panel. Everything has a solid 12v supply, the amp is nearly brand new, and the fuse hasn’t blown. Everything is also thoroughly grounded.

Could anyone chime in and come up with possible solutions/theories?
