Alright, only thing added to stock battery are 2 PIAA driving lights, small LED marker lights & winch. Installing full stereo system & 16ft. of RGB Lighting off 2nd battery. Just got the Aopec Smart Battery Isolator & a larger battery. Have no problem with wiring relays & switches, but is it possible to wire a separate "ignition only" power block off the 2nd battery similar to the stock power block under front rack? I'd like to have the 2nd battery useable for stereo/lighting ONLY when machine is running. Just curious if this setup would render the isolator useless? Not a problem connecting normally, just a preference if anyone has already done this?
