So I was doing some wiring of something under the seat, and I start seeing sparks and smoke coming from the side of the battery tray. The positive battery cable was shorting on the frame, because it was wedged between the frame and the battery tray and the insulation had been worn off. This might be a good thing to check on your MVs because your positive cable may be routed the same way mine was. Luckily for me, I found it before it got any worse and was able to repair the cable and re-route it to avoid any problems in the future. I'll post some pics later.
