My head lights are dim I tried replacing the bulbs my volt gauge keeps jumping from 12.2 to 14.3 volts. I thought it was the altinator but I have no clue what it is I want to get it fix because it is hard to see at night.

Have your charging system checked. If you have a digital multimeter, you can do some testing yourself. Place the meter leads across the battery posts, everything off, including the engine. The generic spec for a full charge is around 12.6 volts. Start the vehicle, take second reading battery posts, second reading should be higher than the first if charging system is working.

Check the voltage reading at headlamps, engine running.

Because you have an electrical load detector on this vehicle, check for applicable trouble codes. Some of the national brand autostores will check codes for free. Also, they should be able to check your charging.

What should the volts be for the head lights?

Close to the same reading as far as the reading across your battery posts, engine running.

The diagram is for a Honda civic cx w/drl. The top wires are voltage for high or low beam. The bottom wire is ground. You have High and low beam fuses in your interior fuse box. You could check voltage at the fuses, engine running, headlamps on.

Was it the same 13.3 volts at the headlamp wiring and across battery posts? Did you check the voltage at the fuse or headlamp wiring?

I couldn't post the whole diagram and make it readable. The whole diagram was too small to read.
