            So if I read this right, you had a c970 and the first thing you did was change the HVT?


            As posted in several threads with this problem, check the blocks, restring the transfer-seperation corona wires and main charger wire with Katun wire off the spool, and the problem will likely go away. Do not use prestrung wires!

                I have stopped responding to these as I have posted this since the 230 and 350 series.... At least 3 years now....
                And Star Trek was just a tv show...yeah right!
