Electrical problems

Does these trucks have 2 alternators or just the big one.
Mine has the big alternator and a smaller regular alternator size of a regular car

The problem I'm having is I cannot get the headlights to work still working on tracing things. Do these trucks have a fuse box

One last question has anyone rewired one. Was thinking on using a painless wiring harness

The truck came stock with a huge 24 volt 60 amp alternator.

No fuse panel stock.

Several people have gone the painless route.

Thanks for the reply going to start acquiring the parts I need to convert to 12 volt then get a new wiring harness
