What exactly is your problem you are trying to troubleshoot? Battery voltage should be 12 volts or slightly higher, stoplight should be 12 volts with brakes on and zero with them off, output voltage would be how much voltage you are sending to the brakes which varies but would be anywhere from zero to 12, and output current will be based on the amount of brake assemblies you have. Most likely between 20 and 30 amps.

If you have a problem the controller should tell you which problem you have.
