New guy here with a problem. I have a 2007 Hurricane with a Workhore chassis and 8.1 engine I bought it new, Two years ago while traveling the charging system went crazy and blew up the battery. We replaced the battery and nursed it home. We were pulling a trailer when the trailer was unpluged it was cured so we thought. This past weekend it did it again but no trailer this time, when I check voltage at the battery with the engine running it's between 16-18 volts but on the dash the computer says it's 12 volts and drops to about 8 volts and then shuts down. Anyone ever experience this problem?? Thank You in advance for any help or info.
