"Why are my parking lights on?"

It's one of the most common questions we hear — and your MASTERCELL NGX can answer it in seconds.

The Switch States screen gives you a real-time view of every switch input on your system. Each input shows a 0 when it's off and a 1 when it's on. Whatever you're chasing — parking lights that won't shut off, a horn that won't sound, a switch that doesn't seem to do anything — you can pull up the screen, find that input, and see exactly what the MASTERCELL is seeing. If an input reads 1 when its switch is off, you've usually got a switch wired wrong or a wire shorted to ground, and now you know right where to look.

But Switch States isn't just for troubleshooting. Because the MASTERCELL NGX reads your switch inputs directly, you can wire and test every switch in your car before you connect a single load to a POWERCELL. Flip a switch, watch the digit change, and confirm your harness is right as you build. It turns a big wiring job into small steps you can check off one at a time.

No laptop. No test light. Just your MASTERCELL and the inSIGHT screen.

This is the next post in our series on the diagnostic tools built into the inSIGHT screen. Read the full breakdown on the blog: https://infinitybox.com/wiring/mastercell-ngx-switch-states/
