Battery Cable Size

Recommended Posts

My 7016 Sovereign with the 16 hp Briggs should have some new battery cables. What size should they be given the amperage requirements of the starter/generator? The ground cable on it now is a lot smaller than the other cable which doesn't make much sense since they both need to carry the same amperage and length is not that different. Want to have then large enough to work well, but no need to get them too big and waste money. Thanks in advance.

I would match the the larger cable to be safe. It doesn't mention cable size anywhere that I am aware of and I am guessing your larger cable to be a #2 size. The runs are fairly short and I don't think the cranking amperage is much over 75. The charging side is roughly 8-10 amps.

I have #10 wire for cables on one of my tractors and haven't had any problems. If the engine starts like it should, you will not overheat this size cable. It will easily carry the charging load.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time
