I was working on trailer lights and got them all resolved, but drained my batteries on then’99 Burb in the process. Put the batteries on chargers and and a short period later it started. Removed the Chargers, but I no longer have running lamps (on the truck). Have brake lights, turn signals and headlights, but not the running lights. I have the owners manual with fuse guide and purpose for every fuse. I’ve pulled and checked every fuse, found one 10A that was burned. Everything else is fine. I’m at a loss here.
