Hello fellow boaters,

I was looking to see if anyone has seen and resolved this problem or have any tips on how to maybe isolate my problem. I thought I had a dead battery when my motor wouldn't respond to turning the ignition key. I put a another good battery on BUT when I connect the negative cable I get a very bad spark. Please help if you can, it's really got me down and depressed.
