I replaced both battery and alternator, got the 150 amp alternator so it’s the right one. I took it to get tested and the new alternator works. So the new battery is installed and the alternator. But no power to the dash or radio. The head lights come on. When I turn the key to start it. It makes one clicking sound. I bought a fuse tester and it seems power is going to my right side fuse box on the passenger side and not the left side fuse box driver side or under the hood fuse box.

We need to know what you're driving to help you, Josh.

If you plan to keep and work on your truck, I highly recommend picking up a repair manual with electrical diagrams.

what kind of fuse tester do you have, and how did you determine that there's no power to the underhood fuse block?
