I own a Ranger 520. The boat has set in my barn about a month since I last used it. I went to check the gas level and had no power. I plugged it up to my charger and one indicator light on the left was blinking. I took the battery to be tested and the battery was dead. I bought a new battery put it in the boat and still nothing. The two breaker switches in the back are turned on. I checked the fuses in the box they are all good. My routine is I put the boat on charge as soon I get it home to charge for a week. Any suggestions would be greatly appreciated?
