I have a 958 and had routed the cable up thru and along the shaft of my terrova. Apparently it had wound itself to tight and I lost the regular 2d first then later in the week I lost the DI. New TD and it all worked perfect again. One more thought, I have also cut thru the TD cable with my braid fishing line, it just looked like a nick however it had cut one of the wires. Both my fault! Been thinking about buying TD by the dozen.LOL
