Battery cut off switch

Have not done the battery in the trunk yet so was just :lurk: up to this point :iconbigg:


The electronic affect on a Bat. disconnect sw, had not even crossed my mind. But, Voltage spikes are never good on any thing.

What about using a one way diode to control the voltage spike. (Think A/C compressor) That little wire that jumps across the connection to control the spike of voltage when the A/C compressor clutch releases.

Now that i have type this.......Has any one took one of these disconnects apart? I would bet there is one in there already from the factory. Yes! No?
