Trying to figure out why all 3 of my ballasts stopped working. All were working just fine after filling them last fall (September). When I flipped the switches to empty the ballasts there was no power to any of the ballasts, all 3 had been working just fine up until that moment. I looked at the fuses to see if maybe fuses had blown but they look fine. Dealership took a quick look at them when they winterized the boat last November and, of course, said it wasn't a simple fix like the fuses and said they would take a closer look at it if I brought it back to them this Spring. Dealership just put a new center ballast motor in 2 years ago because it had burnt out. I guess it could be the ballast motors, but I thought it was just a little odd that all 3 would stop working at the same time after they had all filled just fine out on the lake that day. Thanks for any recommendations.
