Re: minn kota motor problems
If you’re using deep cycle batteries a load tester could damage them. Load testers are for starting batteries that are designed to give short bursts of high current that you need to start an engine. Deep cycles are designed to supply much lower amperages for extended periods of time.
I would also respectfully disagree on that test. In actual use there is no way that motor draws 50 amps and I don’t care what MK says. Too the voltage drop across the terminals will vary substantially depending on the battery’s level of charge. At lower levels of charge you could see as low as 8 volts.
I also know what the documentation says about the voltage necessary to run a fish finder. Years back when I ran the motor and the FF off the same battery I knew when the FF shut down it was time to go home. That is because the motor drew enough to cause a battery voltage to drop below 8.
Please buy an AGM replacement and I’m sure you’ll have less trouble.
