Okay, well I have an update on my battery issue. I went out tonight and tried to recreate my problem and find out where I was losing power. If you do not know what I am talking about, my problem is explained in depth in the thread "Battery Issue." Well here's how it went.
I had fully charged batteries. I cranked the boat up, and checked the voltage - 12.5. I let the boat run for about 5 minutes on idle, out of gear. After this time, voltage - 14V. So I turned her off and plugged in my Humminbird 787 and my Lowrance 510C. I left them on for 45 minutes running. I did not try to crank the boat again during this time (simulated fishing). While this was happening, I kept a voltmeter on the battery, checking it periodically. At the end of the 45 minutes of "fishing" voltage - 12.4V.
I cranked the motor up and it fired right up. I turned it off and cranked it up 5 minutes later, cranked right up again. I decided to crank it up and then turn it off and crank it right back up. I did this and it still fired right up. Finally, I turned it off and cranked it back up, this time choking it. The motor sputtered, and I pressed the gas and it turned over and cranked. I saw the hesitation in the motor, obviously from the added fuel. So I turned it right back off and tried to crank it up again. It spun, but no fire, even with the gas pedal.
So here is my question. Is my problem because of the repeated turn offs of the motor without time to charge, or is it because of "flooding." The reason I ask this is because I usually average at least 30-45 minutes of a fishing hole. Another question is can a flooded motor being hard to crank actually drop a battery that much so that it will barely turn the motor (even without firing)? I ended this experiment at 7:30 EST, and am going to let the motor sit for 30-45 minutes without charging and then try to crank it again and see if it will after flooding has had a chance to subside.
So, am I on the right track or am I thinking completely off base? Also, any suggestions or help will be GREATLY appreciated. I know you guys know your stuff. Thanks in advance.
