Hi Aghakhani,

Just a suggestion whatever you do, make sure the HV Module does not contain any kind of charge, use a HV Probe. I will let you other details as soon as i find out.

What i meant was get a HV Probe, check if that HV has charge now if it does have charge like few thousand volts.. than you need to discharge that stuff either by professional discharge kits, there are few risky options to discharge it as well but you try find proper way.

Hi Brother Aghakhani

It seems to be that you do not have expereince or proper training on defib or HV side.. It is dangerous to do the job without any knowledge on safety issues.. this is not a handyman job..careful do not put patient and your life at risk..Sorry may be I am wrong or harsh on this topic..

My suggestion is to forum administrator need to more closer look on this type of topics and advices going through this forum to prevent incidents..
