Hey all,
My THC just magically stopped working one day. Been in business, well not business, but it’s been working fine for over a year now. Ran through the THC flowchart. Can’t seem to come up with anything. This is where I’m at:
I have verified that it is wired correctly.
When I perform the resting voltage test it returns 0.00v
When I perform the live voltage test I return 0.0 or 0.1 V
When I measure the DV voltage across pins 1 and 2 of the VIM box while firing its returning +2.4 VDC
I have checked continuity between the USB plug and the outer shell of the box. There is none. I have also checked between the USB plug and the slat. Also none.
I then proceeded to test voltage across the A1 pin and the GND pin. I measured no change in voltage when firing the plasma cutter or stationary. I checked the grey and white wires for continuity from the plug to connectors and ensured that the connectors are tight.
I had heard that sometimes its can ground out through the ground pin on a desktop or monitor charging cable. Loaded fire control into my fancy HP victus and trucked it out to the garage. Did the same test, and no changes.
Unfortunately I feel like it’s got to be something internally at the point? I’m constantly checking for continuity between the box and the usb plug, and there isn’t any. I did notice there is a red light on the THC chip, is that normal? Does anyone have any other suggestions for things to check?
Thanks all,
Duncan
