Fuse panel issue

[Rambo2]

Hello all,

I'm still getting accustomed to this amazing site, so please bear with me as I explain the issue I am having with my 1970 GMC C15.

The instrument panel fuse keeps blowing leaving me with no dash lights, tail lights, or fuel gauge (not sure if that is part of the same problem or not). I replaced the headlight switch several months back and have finally gotten a chance to spend some time on it. Also, the battery seems to die pretty quickly if I put the key into the accessory position. If I don't leave the key in accessory, it turns right over and maintains a charge. Again, don't know if this is related or not.

I have a custom stereo in it, but don't see any issue with the wiring there since it was hooked up long before the issue came up and still works when the battery is engaged. The fuse box under the steering column looks to have been altered and the years. I am good at wiring stereos, but fuse panels and accessories going to them are a little out of my comfort zone. I would like to fix it myself, but wonder if I should take it to my local repair shop to be safe.

Any ideas? Any help wild be appreciated. Thanks!
