HV wire

Re: HV wire

The glue was barely touched. The short actually carved a path through the PCB.

The inverter was overdriven by 2V or so. Would that have contributed to the arcing?

Yes it would have.

Re: HV wire

The inverter input should be between 11-12V. Since I am using it in an automotive application, voltage can vary between 11 and 14V. By my calculations, a 5.6Ω ballast resistor should even it out.

Re: HV wire

Ugh! More arcing... this time between the black box and the white connector. This high voltage stuff is tricky.

Re: HV wire

kinda sucks not being able to edit entries...

So I removed all the carbon, thoroughly cleaned the board with solvent, put on several coats of laquer, and surrounded with silicone, plugged it in and ... instant arcing. Bah!

Then I removed ALL the added material down to bare board and leads, plugged it in, and it is completely stable. Nota bene, air is the best dielectric.
