Lincoln IdealArc Tig 250 HF Problems

[treed67]

Ok guys, I got a question. I just bought a used Tig 250 that welds fine, but the HF isn't working. So far I have:

Checked HF Capacitor to be good.

Checked the spark Switch

Checked contact gap

Checked for shorts to ground.

Checked that I am getting 115v to the primary side of the high voltage transformer (with the transformer disconnected.) The problem is that when I connect the primary leads to the high voltage transfomer, I only have around 3 or 4 volts coming into it.

The primary side of the hv transformer measures around6 ohms and the secondary side measures about 8K ohms.

Do I have bad hv transfomer or could something else be breaking down when the transfomer is connected?
