Battery Disconnect

[K9Paco]

I’ve noticed a leak on my second battery so I’m gonna throw a disconnect on to temporarily solve the problem. I’ve seen both ways done but what side should I put it on, +/- ?

I usually put the disconnect on the positive side.

Just like you would install a battery connecting the negative last. Also for spark preventioin.

These are pretty cool have two removable keys.
