It sounds like the problem is in the cables. One or more may be damaged. Run a test on each one with an ohm meter. See if they all check out and we can go from there. I see this problem all the time here. If you need help on how this is done get back to me. All follow ups are included in our fee.
Just checking back in to see if you were able to get this resolved or do you still need additional input from me here?
