Powerhead gets only occasional power
V7+ animal powerhead only gets very occasional power to turn brush. Powerhead has been completely disassembled to the extent necessary for complete cleaning. Unit is pristine. No clogs or hair trapped around spindles. Perfectly clean. I think the problem may be in the swivel wiring, since it began as a position related problem that got worse. I need a wiring diagram for entire powerhead. Any experience and solutions to the same issue would be great.
Is this a good question?
