Here is a quick video on how I installed my on board battery charger. My old one just stopped working but it lasted for more than 5 years so no complaints there. Bass pro actually still had the same model and even though it was a bit expensive, it does a great job. It provides 100% of the available voltage for the three batteries I have installed and does a discharge, condition, and re-charge. So the installation was as easy as it gets however, you will get the idea if you have never done this type of repair.
