6.7 Electrical problem

I have 2012 F350 lariat with 6.7 Powerstroke. Hooked up in bed salter/spreader by hooking ground wire to battery, power wire I alligator clipped on to a wire that had been alligator clipped to a power source out of fuse panel that had an in line fuse on it, that had been installed with snowplow. I had Truck Running, hit power source switch on in bed salter/spreader and my truck died completely no power at all. Inline fuse I had connected to didn't blow. I have cab lights and that's it, checked all fuses but have not replaced any relays. Any suggestions please help, no power at all and I have snow storms moving in and need to plow snow with it.

Do you get anything when you turn the key or is it completely dead?

Do you have 12v at the battery? 12v at this connection you made?

Did you check the amperage draw on the sander motor? I am sure betting it draws more amps than the hydraulic pump on a snow plow. Also betting the wire that was left from the snow plow was smaller gauge than the sander power cable?

Was the polarity correct on the sander motor to your 12v source on the truck? I am sure it was red and black but had to ask. If it was not, and you hooked it up backwards, when you hit the switch, you could have fried the PCM but I would do some poking around with a meter first and see where you do and don't have power like at the starter. If you have 12v at the starter but nothing happening when you turn the key, hummm.

Let me know what you find out.
