Battery cutoff switch on negative terminal?
 

Hi Folks.

I recently relocated my battery to the smugglers box and hate always having to rummage into there to get to my battery negative lead when I am working on the car. I was thinking of installing one of these hella battery cutoffs pictured below. I know that these are traditionally wired on the positive side of the circuit. Does anyone have a reason why I shouldn't wire one in on the negative side?

Thanks.

Mine is wired on the negative side. I can't imagine why one would wire this on the pos. side.

Most ferraris come from the factory with a manual battery cutoff similar to that (at least they did all through the 80s).

They are always on the negative side of the battery.

if you never plan to shut the car off when it's running, as in a requirement for a race car or such, and are just trying to save the battery, then it's fine to hook it up on the negative side..

big difference...

For safety (like racing or fires) wire it up to the POS. side. And if you do, make sure there is a constant power supplied to the ALT. so you don't burn it out. You can also use a relay to disconnect the battery and put the switch where you like to.
