Hello,
Stupid question here because I didn't take a picture before I took them out. What is the correct wiring setup for a 2011 185 sport for the batteries. I assume a positive from the switch goes to each battery and then the 1 negative goes to one of the 2 and you connect to the other negative with the jumper between the 2 batteries. does it matter which battery I put the negative on? A schematic would be great, but I can't find one.
Thanks,
Scott
