I got a 1981/2 yamaha s540ec sled that I screwed up on the other day and left the lights on and drained the battery. So I pulled it and got it started and the light came on, so I turned it off rode it for a while but then the light and heated grips didn't work. Now even with charged battery it won't turn over or even try to. Any ideas?
I just found the book on it is is a 1980 EC540D then it says excel v on hood
