Battery connections

[Kane]

My boat sat at the dock for 2 weeks and my starboard motor turned really slow. Had to flip the parallel switch to get it to fire. The port motor fired right up. After a quick ride they were fine. I have 2 Optima Marine Blue tops. Could someone send a pic of they’re 255 battery setup or verify mine?
Thx!

Your battery cable connection look correct, your negative connectors look clean ,check that your positive cable and battery post are clean. You may just have a bad battery?? Good luck

Batteries are a dealer installed item so there is no consistent standard.
