I have a 2006 Bigdog Mastiff and when I was out riding over the weekend the first problem I ran into was when I went to turn off the bike the bike wanted to continue to run. Once I fired the bike back up to head home as soon as I pulled into my driveway I looked down and my Tech lights were all lite. Then they would go out then all light up again. I turned the bike off and have not started since to check. Any ideas to what this might be?
