You gotta be kidding!
First the foil does a good job of shielding the water and is easy to mold around small areas.
Second..HOW is electrical current going to be passed (shorted) to the foil when the wires are INSULATED, let alone being *hot* when car is turned off. Hell, many people spray the engine bay with the battery terminals and bare wire exposed!
Here read this:
You must cover all sensors, the distributor, spark plug openings and any electrical devices that have the potential for water accumulation (which could cause a short). You're only trying to prevent the majority of the water from getting in; it does not need to be watertight. The engine environment should already be waterproof.
Aluminum foil is an excellent wrap to protect engine components. This works for spray-cleaning, painting and washing. The aluminum foil is easily molded around parts to keep them masked. Since the foil fits tightly, it doesn't hamper your view or make it hard to get into tight spots. It's faster and cheaper to use than tape and fits around odd shapes better than rags or paper
