Stock battery cable size

[kwiksilverz28]

In the process of adding a second battery to my 2006 Sea Ray 185. What size battery cables does Sea Ray use? I am going to reuse the original battery cable to the switch and can not find out what size the cable is to change to a lug to the switch. Anyone know? I will likely just order the rest of the cables the same size..

Re: Stock battery cable size

Look at the actual wire without the insulation.
If it look just a hair larger than 3/16 it is #4
If it is more like 1/4 it is #2
If your are judgmentally handicapped, take a couple of drill bits with you for comparison.

You can't go wrong with #2. Bigger is better in this case.
