Anyone know what the point is for having a grounding strap to the hood?

I never noticed it there until I was wiring up a fuse to my winch when I accidentally used my socket wrench to short out my battery against the strap. Scared the crap out of me.

 

Of the top of my head and without lifting the hood my guess would be they grounded the hood due to the engine compartment light being attached to the hood itself?

Just my guess though.

 

That might be it. I don't have a hood light though.

 

I read that the hood is grounded because it keeps static out of the radio. If the hood is not grounded correctly the rattling around can causes static charges which causes pops and snaps in the audio. Not sure if this is true, just something I read.

 

i have been wondering this myself. thanks for posting about it

 

I agree that $h!t can get out of control

 

I'm sure that there are other reasons that I may be unaware of. But rust prevention is one of the reasons to bond all the metal parts together.

 

i know in airplanes its for lightning and static every door has a grounding strap on it

 

The JK under-hood lights I have seen have both positive and negative wires, and the case is plastic.

 

I couldn't think of the term earlier. But this ground strap is most likely related to "Equipotential Bonding". And it basicaly serves two purposes. One , as I mention earlier, rust prevention. If two different metalick surfaces that are in contact with one another happen to carry different charges, current will flow from one to the other. This current flow promotes rust. Two, the equipotential bond also serves as a grounding plane for electrical systems. Not necessarily to carry the return for electrical circuits. But to facilitate electrical circuit safety. Basicaly, if a hot wire comes in contact with the hood, it will blow a fuse because it is grounded. This is my best guess.
