May be a voltage problem



Did you check the voltage on your Supergun or cabinet?

I use a cabinet and the votages in the input of system 246 are 4?77v and 11?87v.

4.77 is too low should be 5.05 to 5.15

Try raising the voltage if that does not work.



Disassemble the kit and put it back together checking every connection.



Then try again.
