Hey this weekend my optima blue top D34M got so hot it cracked the top and warped the top as well. No wires melted, but it was to hot to touch for about 3-4 minutes. The weird part is that I didn't even have any of my stereo, lights, or other accessories going. Here is a diagram of how I had it hooked up.
This is the 3rd season with the battery and I have never had an issue before. Curious what others have experienced or what else I should consider. I tested with a multimeter the the factory battery with engine off and on, then the Stinger SR200 isolator with the engine on and off and everything was correct voltage wise. I believe I am still in the 18 month prorated warranty period so I can exchange for a new one...but damn I thought it was going to burn my boat down!
Any help would be appreciated.
Thanks.
