Turn your battery terminal into a quick disconnect

Mon Apr 04, 2011 9:04 pm

While looking into adding a quick battery disconnect (to facilitate a reset should any glitches arise, as discussed in other threads), I found one sort-of already in place. Just use a 13mm socket to remove the existing nut and replace it with a 8mm wing nut from home depot and you're good to go! If you're careful to support the right hand side of the assembly while you make the swap you won't even disconnect while doing it...

What happens when your wingnut vibrates loose, because you couldn't get it tight enough???

It won't. I use those cheap quick disconnects on my classic Minis, which are arguably the most rattly cars in existence, and they don't come loose:

Garygid put a lock-washer under his wingnut, just to be on the safe side, but from my experience it just ain't going to happen.

Hi Mike, it looks a little bulky. Will this contraption clear and fit under the Leaf bonnet without knocking around??

Thx.

This is all getting ridiculous! If you feel you need to make this modification to your car, then call your dealer to schedule a service appointment for whatever is going on. I know some are concerned about software issues (which is where this whole disconnect thing began), but really the car is under warranty and covered with roadside assistance. Disconnecting all of the power, thus clearing some or all of the error codes, is not going to help solve the root problem you maybe concerned about or experiencing.

I'm not sure, I've not sat inside the LEAF engine compartment with the hood closed to see how much room remains between the hood and the top of the battery. :lol:

In any case, I'd not necessarily advocate using one of these over simply replacing the existing nut. However, for the sake of a more elegant solution, one might want to consider a steel knob like this one from McMaster Carr instead of a wing-nut:

It's so that the people having the no-start issue can quickly disconnect their battery "in the field" to clear the error and get their car going again.

Why not just just keep a socket and driver handy in the car?

The answer to why, in this case, is quite simply because you can. Yes, you can carry a wrench in the car, but where's the fun in that? :lol:
