Yes, if you short those 2 wires, the fan clutch should engage. When you shorted the 2 wires did the fan clutch operate and the fan engage? Maybe your magnetic clutch is defective if it's drawing too much current. I see your plastic connector is missing. I replaced my broken connectors a few years ago.

When I do oil changes, I like to test my aux. fan switch and clutch fan switch to make they are operating. With the engine running, I put a screwdriver across the connectors and look for the fans to operate.

On another note, I purchased my '93 new and the clutch fan never operated until I replaced the clutch fan temp. switch. Apparently the car came with a defective clutch fan temp. switch.
