I need help in finding a battery cap for my MC1 computer. The one I have now leaks water into the compartment and fries the batteries after each dive. I have checked and replaced the o-rings and that has not taken care of the problem. I have also contacted LP and they stated that the Manf. does not make the cap. any more???? The computer is only 6 years old. Any help in locating one would be greatly appreciated. Thank you.
