No Longer Recharging The Battery...?

My unit has worked fine for about 6 years. Recently I thought I was having battery problems and replaced the battery twice. After the second time I tried manually trickle charging the battery and it worked great-- for about a week. After trial and error a few more times I have determined that the unit is no longer recharging my battery. I changed the fuse, with the same results. Is there a part to replace to address this or does the whole board need to be replaced? Or do I wire in a solar panel to keep the battery up?
