I have a Stinger battery isolator that I’m going to install in a 2012 900 XP and I was wondering what the best "true ignition source" to wire to was? I’ve searched old threads but couldn’t find exactly what I was looking for. Also, is there anything else other than an isolator that I should have to run a second battery? I have inline fuses but saw where some were using circuit breakers rather than carrying fuses. What the best option? Mainly looking for the best "true ignition source" though. Thanks in advance
