Up in smoke

[oldiron]

Well yesterday I pulled my 4x4 out the shop getting ready to go to Jerry Jones get together on Sat. when my truck just stopped running. Then the smoke started to roll out from the dash.
I had no lights no power. I felt under the dash for hot wires and didn't find anything. I checked the master fuse from the battery and it was blown.
I replaced the fuse and checked under the dash again with key off. No smoke or heat.
Then I turned on the key and here comes the smoke again. I have a relay under the dash that connects to a hidden switch that prevents the engine from starting. The relay just started cooking. Turned the key off and pulled the wires going to the engine thinking maybe a wire was shorting out. But when I turned the key on again the relay still got hot. Bad relay. Replaced it.
Now I have no tach, the left turn signal doesn't work and the alternator is charging at 36 volts.
Replaced the alternator and now my tach still doesnt work and the left turn signal works some times. I dont trust the truck enoungh now to travel 900 miles to Jerry's this week.
I'm ready to pull out my hair if I had any left.
