I have an 07 Street Bob that the only electrical work that I did over the winter was installed a power commander V from FuelMoto, and now when I went to start the bike up to take it for a ride it wouldn't turn over than then I smelled something...my battery fried and the positive post had melted off, anyone have any idea why this happened???

 

you have something crossed over somewhere basicly made the possitive touch the negitive somewhere in the path, that would cause what you are describing. got lucky man i have seen them explode

 

Yup. Is the PCV a straight plug in so there's no way you could get it crossed up? If so I'd look to see if you accidentally moved the battery so that the positive terminal hit the frame or batt box.

 

I bet your battery had just reached the end of its life, corroded or whatnot...installing the PCV with it's one harness plug shouldn't be much of a recipe to electrical disaster, unless you really went to town yanking all those under-seat cables around due to frustration trying to relocate the harness (I know I just about did).

 

yup pretty sure the battery was at the end of its life, I got a new one and it fired right up

 

Batteries don't just fry like that. They do that because something was shorted. Perhaps when you replaced it you fixed the short without knowing it, but I guarantee you that the smell was caused by a short.

 

There isn't much space at all between my positive terminal and the battery box frame. I added a chunk of rubber to be on the safe side so I didn't have that exact problem happen.

Glad the new battery worked, but you should double check the clearance.

 

Definitley a +1 on that. Check it out or have it checked out, something ain't right, it could poss blow you to christendom or burst into flames whilst on the move. Not tying to worry you or anything ......... You may well have inadvertantly fixed it - but get it checked out would be my advice.

Well thanks guys I'm planning to bring it down to my local indy this afternoon to have him take a look at it to see if he could find anything wrong with it.

 

You do have the rubber cap on the positive terminal right? Check all around the terminals on the frame and metal parts for signs of arcing.
