I have twin 4-236 perkins.* My batteries are mounted on the Stb side of my boat about a ten foot (one way) run from the starting battery to my port starter.
I was having a few issues with slow starting on my port engine so I replaced the positive starter cable and upsized from a 1/0 to a 3/0 cable.**Saw some improvment, the engine always starts in a second or two,*but still turns over a little slower than the stb one does.
I had a marine electrician on board doing some bonding work and he said he felt that I need to upsize my ground wire to the port*engine as well, it is still 1/0.*
He also felt that I should go up to 3/0 on the starboard engine.* When I asked him why (it turns over really fast and fires right up) he said it was "just better."
Two questions:
1. Should upsizing the ground cable to the port engine lessen the voltage drop?
2. Is there a good reason to spend $150 on cable on my Stb. engine?
Thanks
