if a battery cable gets any internal corrosion, the cable in that area will get stiff and hard. You cut the insulation open and its green or black corrosion on the copper. See it all the time with Yamaha outboards. I use a load tester to check the battery cables. If the battery passes load test, I check it at the engine, if it fails at the engine, I start checking components between the two, one at a time. If I think the cable is bad, I'll work the cable back and forth, if you find a bulging area, or stiff area in the cable, its most likely bad at that point. Battery switches can go bad as well. Putting a bad battery with a good battery can screw things up also. You can use a good set of jumper cables to test the circuit as well. From the sound of it, I'd check that starter. Make sure the mounting bolts are tight and the ground cable to the starter is good
