Precharge and HV circuit

Post by nikejamie »

Hi guys

I have the gigavac gv242mab contractors and resistors.

What do the red, black, white and blue wires do?

Does anyone have a precharge and HV circuit we can follow?

Thanks

Both wires leed to coils. One pair is for hard turnon and the other pair is for holding.
