I don't have Sled with me but I'm a little confused. Should not have changed anything with coolant line when you added battery. Did u mount battery tray to chain case? Maybe a pic to refresh my memory?
I found this picture online

Looking at that pic I can tell that mine is broken at the bolt just above the slot. Guess, I need to get a new one....more parts, more parts....
The battery strap clips to the chain case cover "?the back". Look for a little lip. I can see it in the pic above right next to e brake.
