Noob aux lights battery question

[Martindfletcher]

So, disconnect the main battery, remove the battery, then disconnect the secondary battery??? Edit: because you can't access the secondary battery unless you completely remove the main battery.

You need to disconnect the ground that goes to the frame also from neg battery connector, not just the neg connector from battery.

Once you look at it you can see the ground path that exists after unhooking from battery. It needs to be completely ungrounded.

The 2nd batter has cables running to the main battery you do not have to remove main battery.

Rhinebeck and some other dude have super detailed posts on this somewhere.

Super helpful. Thanks to everyone here esp @Ldybug. I found the post about disconnecting all power as well:

@jlewissystem is it okay to ground more than 1 item to the same bolt or is that a no-no?

OK - after some time has passed talking about this subject and i got off my arse to hookup some MOAR LYTES, i added some additional grounds up front. I have detailed in our build thread, but here are a few pics.
