To diagnose safely you need a variac & AC amp meter.

1) unplug the degausser.
2) hook meter in series with AC line.
3) plug in to variac set at apx 90 V
4) turn on but DONT let the meter go above 1 amp.
If it draws over an amp its 95% HV.
If it stays on its 95% power supply.
Sometime a set wont start at 90 V. turn up a little at a time till it starts.

I have a couple questions about this before I mess with with this set. Luckily I do have a variac and plenty of meters so this shouldn't be too bad. Anyways I am not sure how to put the meter in series with the AC line. Am I hooking the positive lead to one side of the AC line, and the Negative to the other? I am afraid of blowing the meter honestly.

Also I am a bit confused what you mean by "95%". Do you mean that it's a 95% chance that is the issue? May be a stupid question but I am trying to not miss a single detail in the instructions to ensure the right results and to avoid damaging anything.


Also not sure if this helps but this set is 19".
