LeRoy, I've learned that only use the OEM HV Bleeder assys fromZenith. I
have tried all the aftermarket stuff. very high failure rates.
You can check with TriTronics (800-638-3328), or Zenith direct.(
888-393-6484)
Zenith ships no S/H . Just a bit cheaper there. Get the OEM...You would
be surprized at the price. That's your fix.
