I was getting my bx2350 ready for spring and it started right up after winter. I cleaned up the battery cables and topped off the battery with distilled water. Then it would not start , totally dead. I charged the battery to full charge, still nothing. I took the battery to 2 separate places and they both said it was a good battery. After doing some investigating as to whether a battery showing full charge could still be bad, I went and bought a new battery. Still nothing except, a beeping sound when I turn on the flashing lights. Any ideas would be appreciated. Thanks
