gauge wiring

[bigd65]

First problem
OK, I thought I was going to have this thing nailed. I had all the wiring figured out. The green wire went to the temp sender,the blue wire to the oil sender the brown wire was still hooked to the alternator for the volt gauge and the tan wire to the fuel tank. The senders for the oil and temp are new, the fuel is still working ( I believe ) but the gauges for the temp, oil max out as soon as I turn the key on. The volt gauge still does not move.

I used a test light and have power from the temp gauge wire (bright light on the test light). The oil sender wire has power but the test light is dim. The volt gauge I dont know what to say, there is power going to it but the gauge does not move.

Second Problem
Then the POWER DISTRIBUTION BLOCK. I do not have the buss bar in between the two terminals, therefore I put an in-line fuse (10amp) and connected them with the fuse link. The red wire from the alternator is hooked to the small pin on the distribution block with the wire that goes back to the blower motor switch. The other wire, I think, powers the gauges (if Im correct) its hooked to the larger pin with the red wire that goes back to the wiring cluster on the fire wall.

Well the fuse blows when I mess with the two wire plug on the alternator. If I leave it, it dont blow the fuse. The fuse I am referring to is the fuse link I put between the two terminals on the Distribution block. I un plugged the alternator, the engine was not running, and when I plug it back in, it blows the fuse.

I have something wrong here that I thought I had all figured out and the only think I got done correctly was the plugs and wires. Truck runs great just no gauges.
