Hi fellas! My name is lance new to forum.i have a new to me 09 br and wondering how sensitive the electrical/ computer is? Reason being i have a 12volt sprayer hooked up with wires ran to battery(alligator clips).i should have made a plug for 12v aux.the reason i came here to ask is two fold.one i got better information searching lnfo on correct oil here than other forums.and two i seen members with issues with sensors,pc codes etc and thought it might not be a good idea to hook sprayer up that way.so is the system sensitive?and i seen a thread where a member had a shift issue 2-3 and said a better battery corrected.i have that intermittent issue but only seen that one thread with that response.thanks in advance for tips and advice!
