I need some help, before I dig into the circuit board inside the EVI Power Pack that I wired to 240V AC
but got no response, even after pushing the test button to simulate an EV had connected to the AVCON pilot signal. I checked that the unit received the proper 120+120V (because the internal transformer to power the logic board is wired to receive 120V, which is odd since it has two 120V windings that are in parallel, instead of putting them in series for 240V, but oh well. I checked the output from its internal power supply and saw that the transformer delivers about +/- 16V AC that gets rectified and regulated by a simple LDO to 12V, so it appears that the circuit receives power, but the many chips on the board I did not check yet, hoping to find someone who either has a schematic or who has experience trouble-shooting those old units.
