I'm no mechanic, but one thing in my vehicle's I don't fool with is battery's. I give them wide berth...and respect. If your Cruiser is new, and if you cannot take it back, call your dealer and have them bring you a new one. Crossroads can't help with this as it is a device added after delivery to dealer. If at all possible let them inspect it and make sure there are absolutely no other problems besides the battery. JMHO.
