7720 combine hooking up new lights and most do not work after hooking up

Not to sound like a dick but could your post be anymore vague? What kind of lights? where you getting your power supply? where are you grounding them? If they have power and ground they'll work, only place that'll be tricky is if they are LED because they are polarity sensitive.

He did say it was on a 7720 combine. It would have been more interesting if he left that out.

It sounds like possibly some of the components designed to bring power to your bulbs are not working, or the bulbs are not functioning.

make sure the light switch is good, check harness on the back side to make sure wires aren't burnt or mice haven't eaten the wires.

make sure the circuit breakers on the firewall are working.
