Quote: Just put the disconnect on the ground cable
The alternator will continue to supply voltage to the motor through the various engine to body grounds so shutting the switch off will not kill the supply of electrons to the ignition, trust me on that All electron flow from batterys is from the negative post through that cable to the to the motor and returns to the positive post of the battery, not from the positive to the negative like most people think That makes the negative cable not a good idea to hook up to the cut off switch
Wouldnt matter anyways... after you start the car you can take the battery out and it'll run fine.. it has to open the alt output circuit
