Battery grounding issue
Hello! Recent owner of a 1986 Aspencade here - completely stock. I was going doing the highway and the bike completely cut out on me, like I turned off the key. I tried restarting it, and the starter barely turned, not nearly enough to start the engine. I waited a few minutes and tried starting it again, and I got a bit more power out of the starter, but still not enough. Towed home, and then it started.
I'm aware of the common stator issue on these bikes, but I don't think that's it. I was talking to one of my friends (electrical engineer), and he guessed the battery wasn't grounding somewhere, which is why waiting and letting it regain a surface charge did the trick. It starts and rides fine now, but I hesitate to take it further than around the block since I don't have an easy way of towing it. I haven't had a chance to do anything with it yet - what do you guys think? I'm familiar with motorcycles, but not as much ones with all the electrics like a Goldwing has. The battery is a year old.
Thanks in advance!
