Diode testing questions..

I had a High Voltage system with a bad diode. it was shorted, and was arcing to ground from the capacitor..
So I bought a couple of new ones. I threw the first new one on and I got no change.
So I tested it and from the Anode to the cathode it reads open and from the Cathode to the Anode it reads open.
I should be getting Closed from Anode to Cathode. An Open vise versa.
I tested it with a Diode tester and instead of a voltage drop it tells me it's open.
Okay, no big deal, my transformer or cap probably blew the diode.
So I check the other new one and it's also open both ways. So either I'm testing the diodes wrong or got two faulty "new" diodes.
What do the Late Night Electronic technicians of the OT think?

Just go buy a new vibrator instead of trying to fix the old one. They're not that expensive.

Wut?
Just get a new one whatever you are talking about gheez

Somehow this seems appropriate
So now what exactly was arcing from where to where?

Or your tester isn't putting out a high enough voltage to exceed the threshold voltage of the diodes, in which case it would read open both ways.

was gonna tell you to boost the voltage, but redneck dude is much smarter than he sounds. kudos to him and good luck to you.

My mind saw "Dildo Testers" in the thread title. I am tired and that was a bit of wishful thinking; howerver, I am dissappointed.
