Battery Cut Off Switch- 60 Cadillac

[Jon Riley #13576]

Hi, 

I have a new battery cut off switch, the one that connects to the battery terminal with a rotating knob. 

My question is, which side of the battery should this go on?  Positive or negative?

Which ever side fits better. Functionally, there is no difference.

A mechanic a knew said that it was safer to put it on the ground terminal. His thinking was that you would avoid arcing if part of the car for whatever reason contacted the hot side.

As a general rule it is always best to remove the ground side of the battery terminal when using tools, because if the tool should touch ground anywhere while also touching the battery terminal you would short out the battery. 

If there is a possibility that could happen with this cut out switch then put it on the ground side of the battery.  Otherwise it does not matter.

On the ground side, definitely.  In fact, I'll wager that you'll find the "switch" is sized to fit the GROUND post, not the Positive.  (Hmmm.. well, if you have positive ground system, that might be an issue!)

Thanks guys.

I will put in on the negative terminal.
